7:15 PM PT -- The Sacramento Kings tell TMZ Sports, "We are aware of the report and are gathering additional information. We have no further comment at this time." Sacramento Kings head coach Luke Walton is being sued for sexually assaulting a woman, who claims he forced himself on her in his hotel room ... this according to a new lawsuit. 

In legal docs, obtained by TMZ Sports, Kelli Tennant claims -- while Walton was an assistant coach for the Golden State Warriors -- he asked her to come meet him at his Santa Monica hotel to drop off a book she had published. Walton worked for the Warriors until April 2016, when he left to become the head coach of the Lakers. She says the 2 had a business relationship that went back several years and that's why she had asked him to write a foreword in her book.

In the suit, Tennant says when she arrived at Walton's hotel, he convinced her to come up to his room so they could "catch up." She claims when they got up to his room, Walton suddenly pinned her to the bed, placing his hips and legs over her body.

In the docs, Tennant claims Walton then began forcing kisses on her neck, face and chest. She claims she screamed for him to stop and tried to free herself, but he held her down, groped her breasts and groin, and rubbed his erection on her leg.

She says he eventually relented and let her get up from the bed, but as she was walking towards the door to leave he grabbed her from behind and again forced his body up against hers. 

Tennant claims when Walton finally released his grasp, she opened the door and left, but could hear him say, "Good to see you."

Tennant claims she did not initially report Walton's conduct but was forced to continually interact with him because of her job. She says each time she saw him, Walton would impose himself on her with a big hug or a kiss, even though she thought she made it clear his advances were unwanted. 

In the suit, Tennant claims in May 2017 -- while Walton was the head coach of the Lakers --  Walton greeted her by uttering, "vulgar, guttural sounds at her" and said, "mmmm ... you're killing me in that dress." She says he then forced an aggressive hug on her and rubbed his body against hers.

It's unclear, based on the docs, what finally prompted Tennant to come forward with her allegations.

Luke recently left his position as head coach of the Los Angeles Lakers and is now coaching the Sacramento Kings.

We got Luke and his wife out in Los Angeles over the weekend, but he didn't want to talk to our guy ... and it's unclear if he knew about the lawsuit.

We reached out to Walton's reps for comment ... so far, no word back.

Amir Khan quit in the ring ... and he needs to man the hell up and apologize to boxing fans, so says boxing legend Roy Jones Jr. 

Khan bowed out in the 6th round of his fight with Terence Crawford this weekend after getting hit below the belt ... insisting he was seriously hurt, and couldn't continue.

But, fans felt cheated by the ending ... and they were pissed.

And, they damn sure should be, according to Roy ... who says Khan flat out waved the white flag.

"Amir Khan quit."

Jones Jr. -- a multiple time world champ across 4 weight classes -- says he would NEVER quit inside the ring.

"When I go in the ring. Carry me out. I don't wanna go out on my feet if I lost. Carry me out. I rather give it all, or get it all taken away from me."

Still, RJJ says all ain't lost for Khan -- a fighter he likes and respects -- as long as he gets real about what happened.

"Amir, I love you as a fighter. I respect you since you were an amateur fighter. You went up 2 weight classes, took on Canelo. You did a lot of beautiful things to show that you have courage," Jones Jr. says.

"This time you were in a no-win situation, and you refused to continue," Jones tells us ... "You stopped at a time we know you could've given more. You didn't give it to us, the fans, your all."

"You have to apologize. We respect that. Be a man. Be honest for what you did, and move forward."

Forget watches, luggage and fancy booze ... Russell Wilson just thanked his Seahawks offensive line with the most Prime gift ever -- $12,000 in Amazon stock each!!

Remember, Wilson just signed a 4-year, $140 MILLION contract -- making the QB the highest paid player in the NFL. 

So, to thank the guys who protect his ass, Russell busted out the credit card and spent a grand total of $156,000 on his 13 offensive linemen, TMZ Sports has learned. 

Each player got a letter with the stock gift explaining why #3 hooked them up. 

"Every Sunday we go to battle together," Wilson wrote ... "You sacrifice your physical and mental well-being to protect me, which in turn allows me to provide and care for my family."

"This does not go unnoticed and it is never forgotten."

Russell says he wants to help his teammates prepare for life after football and believes stock in Amazon will help these players achieve their dreams.

"When I sat down to think of ways to honor your dedication a dozen different ideas came to mind. Some were flashy, some were cool, but I wanted to give you something that had a lasting impact. Something that would affect the lives of you, your family, and your children."

"You have invested in my life ... this is my investment into yours."

The Seahawks play their 1st regular season game on Sept. 8 -- we'll see if his investment pays off! 

Ezekiel Elliott will NEVER forget what he looked like when he dominated the NFL ... 'cause the Dallas Cowboys superstar got his own mug tatted on his leg!!!

The NFL's leading rusher just got the ink done this month ... and it's massive -- taking up nearly all of the outside of his (very muscular) calf.

The pic is a twist on a famous shot of a helmet-less Zeke ... with zombie eyes and a crown on top of his trademark afro.

Seems Zeke LOVES the artwork ... he put it on full display while hanging out with Von Miller and Erroll Spence at Miller's charity event this past weekend.

Of course, Zeke has some pretty unique ink all over his body -- there's an Ohio State logo on his shoulder, a portrait of his mom on his chest and even one of his dogs on his forearm.

Begs the question ... where's he gonna put the Dak Prescott one next?!?!

Think Olivia Culpo is gonna let her ex-BF shame her out of posting hot photos on social media? 

HELL NO!!

Just a few days after Danny Amendola bitched about Olivia's obsession with posting her life on Instagram -- the former Miss Universe doubled down ... posting another bikini pic on IG. 

Remember, Amendola said Olivia's choice to live her life in the public eye was a "fundamental difference" in their relationship. 

"Olivia chooses and wants to be noticed on the internet and in Hollywood to make money. Which was hard for me to understand but quickly had to learn," Amendola wrote.

But, Culpo wouldn't be detoured ... and Monday morning, posted an Easter pic from her family trip to Palm Springs ... and she just so happens to be in a bikini. 

You want attention? You got it! 

Amendola deleted his giant rant -- and replaced it with a message that read, "Fake people have an image to maintain. The real ones jus don't care."

That's when Amendola's former Patriots teammate, Julian Edelman, decided to chime in -- "Get off Instagram please ... thanks."

That post has been removed too. 

Freddie Mitchell HATED his playing days with Donovan McNabb ... telling TMZ Sports the Eagles QB was a jealous hater who cost him $40 MILLION!!!

"He hated that people loved me more than him," FredEx says.

Of course, Freddie played with D-Mac for 4 seasons from 2001 to 2004 in Philly ... and while it might have seemed like the guys got along back then -- Freddie tells us that ain't the case.

Mitchell says McNabb was jealous of anybody who got more shine than him on the Eagles -- so much so, Mitchell says the QB straight-up refused to throw him the ball!!

In fact, Freddie tells us he thinks Donovan cost him and his family between $20 and $40 MILLION because of his antics ... saying, "It cost me a second contract, you know?"

Freddie is just the latest Eagle to come clean with his hatred toward the legendary Philly QB ... All-Pro right tackle Lane Johnson just called him a snake a few days ago.

And why? It all stems from McNabb saying Carson Wentz should be benched if he can't lead the Eagles past the second round of the playoffs.

For his part, Donovan doesn't seem bothered by the all the talk ... he posted a "Winning!" GIF on Twitter on Sunday night with a caption saying, "Deal with it."

Man ... we've come a long way from 4th-and-26.

Terence Crawford tells TMZ Sports ... Amir Khan was SMART to quit in the 6th round -- because the beating was only gonna get WORSE for the fighter. 

We spoke with "Bud" about that smackdown he put on Khan on Saturday -- in a fight where Khan quit after taking an accidental low blow. 

Crawford says Amir essentially "took the easy way out" -- because Terence was finally starting to open up and the beating was only going to get worse. 

"I honestly feel like [Amir's trainer] stopped him before anything bad happened to him."

Crawford says Amir will have to live with his decision to quit for years because it's "something people will talk about for ages."

We also spoke with Crawford about the next big fight ... a potential matchup with superstar Errol Spence. 

EVERYONE wants to see it -- but a behind-the-scenes feud between Crawford's promoter Bob Arum and Errol's promoter Al Haymon could prevent the fight from going down. 

Crawford says he hopes everybody can be "adults" about the situation -- and if they are, he's confident the fight can get made. 

#FingersCrossed

Check out the full interview with Crawford tonight on "TMZ Sports" -- which airs weeknights on FS1. 

*WARNING -- GAME OF THRONES SPOILER AHEAD!*

Arya Stark finally got her freak on in "Game of Thrones" Sunday night ... and while a lot of people were shocked to watch the scene unfold, Josh Hart says she deserves her PROPS!! 

"Get it how you live, shorty!!"

Remember, the whole point of the scene is Arya thinks she could die in the Battle of Winterfell and she doesn't want to go out as a virgin. 

So, she tracks down Gendry (hot guy) and bangs it out. Good times! 

The scene was super controversial since nobody knows Arya's age (are there consent laws in Westeros?) ... and people flooded to Wikipedia to make sure the actress, Maisie Williams, is over 18. 

Don't worry, she is. 

Hart is a hardcore 'Thrones' fan -- so, we asked for his take ... and he seemed PROUD of the youngest Stark girl, supporting her decision to go out and get what she wants. 

Oh, and who does Josh think will DIE before the series wraps up? He's got some thoughts ... 

Atlanta Falcons legend Roddy White was arrested in Georgia earlier this month -- after he was pulled over for a stupid carpool lane mishap ... and cops noticed a warrant out for his arrest. 

Gwinnett County police officers say they saw the 37-year-old WR crossing the double lines to enter the carpool lane on I-85 on April 12 -- a big no-no -- and claimed Roddy's bonehead move put other drivers in danger. 

During the stop, cops ran Roddy's name in the system and that's when things went from bad to worse ... 

Turns out, there's a warrant out for Roddy -- who allegedly blew off a court date from a previous legal situation. 

Cops say Roddy's driver's license had also been suspended -- so, he was arrested and hauled to a nearby station where he was booked and processed. His car, an Audi A8L, was impounded.

Unclear what the previous violation is ... but it seems to be another traffic-related incident since his license was suspended. 

The whole thing sounds VERY similar to the case of Jacksonville Jaguars running back Leonard Fournette -- who was arrested in Florida earlier this month when a routine traffic stop revealed a warrant and suspended license too. 

In Fournette's case, he had failed to pay a speeding ticket -- and then failed to show up to court. When he was stopped on April 11, cops handcuffed him at a car wash and took him in. 

Fournette later paid the fine and now the case is closed. Seems like White will have a similar outcome. 

We reached out to Roddy for comment -- so far, no word back. 

White is one of the best receivers in Falcons history -- dude caught 808 passes for 10,863 yards and 63 TDs in his 11-year career.

A former UFC fighter was hit by a car and killed in Brazil after officials say he got into an argument with his rideshare driver. 

The fighter is 26-year-old Rodrigo de Lima -- who fought Neil Magny in 2014 and Efrain Escudero in 2015 during his stint in the UFC. He lost both of those fights. 

Rodrigo was a passenger in a car in Belem, Brazil when he got into an argument with the driver. According to reports, the driver stopped the car and booted de Lima from the vehicle. 

Once outside the car, the driver allegedly drove away from the scene -- then turned around and struck de Lima from behind, killing the fighter. 

There are reports the driver was working for Uber at the time of the incident. We've called Uber to confirm but so far, no word back. 

Officials are currently on the hunt for the driver. De Lima is survived by his wife and two young children. 

De Lima was 9-3-1 as a pro -- and earned the nickname "Monstro" (which means monster) -- due to his fighting style. 

R.I.P.

Here's Rob Gronkowski showing he's still got a little football in him after retiring from the NFL -- throwing passes to fans in the Bahamas this weekend ... and showing off the scar from his back surgery. 

Gronk and his swimsuit model girlfriend, Camille Kostek, spent Easter weekend right by the beach -- taking in some sun at a fancy resort in Nassau ... it's gorgeous. 

Kostek shot footage of a shirtless Gronk playing catch with some kids -- and you can see the scar on his lower back from the procedure he underwent in Dec. 2016 to treat a herniated disc. 

Gronk returned the following season and had a monster year -- he was named a 1st Team All-Pro in 2017. Pretty amazing comeback. 

But now, it's a wrap for Gronk ... he officially announced his retirement from the NFL back in March and says he's excited for the next phase of his life. 

And, if that phase includes more beaches, more partying and more Camille ... who can blame the guy!? 

Forget Rookie of the Year ... Darius Leonard is now Good Samaritan of the Year -- 'cause the Colts star linebacker pulled off on the side of the road to help a woman change her tire!!

It all went down this past weekend ... when a woman clearly needed an assist with a busted wheel on her Buick.

Enter 23-year-old Leonard -- the AFC's 6"2', 234-pound Rookie Of The Year -- who got down on his hands and knees to help the woman out!!!

@Colts Darius Leonard continues to be an outstanding player on and off the field. So thankful to God that he stopped and helped me. Much love! pic.twitter.com/EKdmpCdYbH

Leonard seemed to have no problem gettin' dirty ... he was crawling through some thick grass to make sure the tire was changed properly.

As for the woman ... she was grateful for the awesome gesture, saying to the linebacker, "Thank the lord for angels!"

It's just another good mark on Leonard's awesome resume ... the dude's done nothing but kill it since entering the NFL -- 'memba when he had 163 tackles and 7 sacks last season!!!

#BEAST

Alonzo Mourning had 7,137 rebounds during his NBA career ... and now he can add one more to the list. 

The 49-year-old was spotted cruising the beach in Miami with a new lady on his arm -- just months after splitting with his wife of 22 years. 

Back in February, it was reported Zo and Tracy Wilson Mourning decided to separate and move forward with a divorce. The two had met back in 1980 and had 3 kids together. 

Alonzo made a TON of money during their relationship -- reportedly raking in more than $147 MILLION during his NBA career, not including endorsement money. 

But, it seems the former NBA star is moving on ... because he was arm-in-arm with a new lady on Miami Beach during Easter weekend. 

Oh, and Zo looks JACKED! 

It's been more than 10 years since Mourning last played in the NBA -- but he still looks pretty solid. 

Zo was a 7-time All-Star during his 15-year career. He was a title with the Miami Heat back in 2006. 

Mourning was inducted into the NBA Hall of Fame back in 2014 and now works in the Heat front office as a player development guy. 

As for the identity of the new woman -- it's a mystery so far but one thing's for sure -- SOMEONE NEEDS TO REFILL THAT MARTINI GLASS!
