Dallas Mavericks

All eyes were on Jimmy Butler's butt Wednesday night ... 'cause his shorts had a dark yellow stain on 'em -- leading many to believe he had crapped himself mid-game.

The unfortunate scene for the new Warriors star played out as he and Golden State were fighting to pull off a win vs. the Mavericks at the American Airlines Center in Dallas.

Eagle-eyed viewers of the tilt noticed that as Butler was making a drive to the lane with the Dubs down 109-107 late in the fourth quarter ... some unusual coloring had appeared on his white shorts.

The Luka Doncic trade to the Lakers sent shock waves through the NBA ... and the worth of his debut jersey could create even more, 'cause TMZ Sports is told the threads could fetch up to one million dollars!

David Kohler, founder of SCP auctions -- who also has arguably the most impressive personal collection of Lake Show memorabilia -- tells us the purple and gold Lakers jersey donned by Doncic is likely worth "500K to 1 million" at auction.

It's unclear if the 25-year-old NBA superstar rocked the same jersey throughout the whole contest or if he switched out at the half ... but either way, the jersey would still fetch a fortune.

A Dallas Mavericks fan was booted from the team's home matchup against the Sacramento Kings on Monday ... 'cause apparently calling for the GM to be fired for trading away Luka Doncic is a big no-no.

It all went down at the American Airlines Center, where at least two Dallas supporters made their frustrations with Nico Harrison crystal clear.

They had two bright poster boards that read "Fire Nico" on them ... but if that wasn't enough, one of the guys also took advantage of a karaoke segment on the scoreboard to really bring it home.

The Dallas Mavericks are pulling a shocking move -- offering refunds to season-ticket holders who want out of their plans following the Luka Doncic trade.

News of the team's gesture made rounds on Tuesday ... after plenty of Dallas fans expressed their disproval over sending the 25-year-old face of the franchise to the L.A. Lakers for Anthony Davis.

Apparently so many reacted by wanting to part ways with their seats, the Mavs want to make peace with the frustrated supporters ... by handing out checks for the remaining home games on the schedule this season.

Luka Doncic is opening up on the trade that sent shockwaves through the NBA world ... admitting getting shipped to the Lakers was a huge hit on his emotions, but he's excited for a "fresh start" in L.A.

The 25-year-old global sensation was introduced to the media for the first time as a member of the Lakers on Tuesday ... where he talked all about the whirlwind past few days.

Doncic said he was nearly asleep when he got word of the trade ... and understandably, the news hit him "really hard" emotionally, with the past few days feeling like a month.

Tons of Dallas Maverick fans are still shocked over losing former superstar player Luka Doncic ... and that includes Texas native Patrick Mahomes, who said the blockbuster deal with the Lakers rocked him.

The Chiefs signal caller met with the media Monday for Super Bowl opening night, where he was asked about his hometown team trading away the 25-year-old phenom to L.A. in exchange for Anthony Davis, Max Christie and the Lakers' 2029 first-round pick.

"I've watched him since he was 18 years old," he said. "I remember going to practice, and it was Dirk [Nowitzki], and seeing his maturation and how great of a basketball player he's became it's been fun to watch."

Kyrie Irving's serving up hard life lessons to young hoops fans, including the golden rule: With great seats, comes great responsibility ... to duck when loose balls come flying at your head!!!

Kyrie's Dallas Mavericks were playing the Boston Celtics Saturday night, when he uncorked a wild cross-court pass that missed his teammates ... but nailed a kid who was sitting courtside.

The poor young fan wasn't looking when the basketball blew up his world, leaving the kid dazed and confused for a few moments. Mavericks staff quickly tended to the fan, whose nose seemed to be bleeding.

Shedeur Sanders added a bit more fuel to all of the Deion-to-the-Dallas-Cowboys speculation on Tuesday night ... as he made a somewhat peculiar appearance at the Mavericks game in Big D.

The Colorado Buffaloes quarterback scooped up courtside seats for Dallas' tilt with the Nuggets at American Airlines Center ... and even though he's a native of Texas, the timing of his decision to hit the town sure got Cowboys fans buzzing.

Jerry Jones' team, of course, is looking for a new head coach after parting ways with Mike McCarthy on Monday -- and a whole lot of internet detectives wondered out loud if Shedeur's emergence in Dallas this week means his dad could very well be Jerry's next man up.

Luka Doncic wasn't just droppin' buckets on Tuesday ... the NBA star seemingly mouthed a soap-worthy phrase after receiving a controversial technical foul.

The apparent remark happened during the NBA Cup matchup between the Memphis Grizzlies and Dallas Mavericks at the American Airlines Center ... when a referee whistled a foul on the 6'7" guard as he was defending Ja Morant.

Doncic disagreed with the call and waved off the ref ... and the gesture resulted in his fifth tech of the season.

Klay Thompson returned to The Bay for the first time as a Dallas Maverick -- facing the Warriors -- and after knocking down a big 3, the 4x NBA champ mimicked his old teammate Steph Curry's infamous shimmy.

But, the Chef got the last laugh.

The intense game went down Tuesday night at the Chase Center in San Francisco, Thompson's first matchup against his former team since trading him in July after 11 seasons.

LeBron James' 22nd year in the NBA needs to be his last -- at least that's what Mark Cuban's saying ... 'cause he tells TMZ Sports the King is just too damn good!!

We caught up with the Dallas Mavericks minority owner out in NYC this week ... and asked all about the Lakers superstar's future.

Needless to say, Cuban thinks it's time for James to wrap it up.

A Boston Celtics mural in Massachusetts that was defaced by some jerks just got a facelift -- getting a fresh coat of Joe Mazulla's grill to hide all the vandalism!!

The OG art -- displayed in Cambridge -- featured Jayson Tatum, Derrick White, Jaylen Brown and Mazzulla ... but at some point during the Celtics' playoff run the last few weeks, it was destroyed by a curmudgeon.

In pics of the defacement, obtained by TMZ Sports ... you can see the individual scribbled, among other things, "F*** Celtics" all over the image of Tatum.

The 2024 Celtics easily handled the Dallas Mavericks. But, how would Jayson Tatum and Jaylen Brown's squad do against the last Boston team to bring a title to Beantown? We asked NBA champ Eddie House!

Not only was the longtime pro a member of the '08 team (he played for BOS from 2007 to 2010), he's also close to this year's Celtics ... he covers the team for NBC in Boston.

So, put Tatum, Brown, Derrick White, Jrue Holiday, Kristaps Porzingis, Al Horford and the rest of the hoopers on a court against Ray Allen, Kevin Garnett, Paul Pierce, Rajon Rondo and the rest of the '08 team, WHO WINS?!

"We win," Eddie said of his 2007-2008 team ... before explaining his rationale.

"We're not going to allow them to shoot all them threes. We're going to run them off the threes. And I feel like defensively, we were a better team defensively. Now, offensively, because of the threes and the way the game is played now, I'll give them the edge [offensively]," House explained.

"But we're going to knock that down. We're going to make it a drag-out game. And if it's a close game, I'm putting the ball in Paul Pierce's hands and I feel like he's going to deliver every single time. But don't get it twisted. I love this team."

Bottom line ... House isn't throwing shade. He simply believes that out of the two super-talented squads, his would emerge victorious.

There's much more with House ... we asked the NBA champ what the often maligned (during the Finals, at least) Luka Doncic must do if he wants to win a championship. We also discussed whether or not the treatment of Kyrie Irving crossed a line.

Plus, we asked Eddie about his hoops star son, Jaelen House, who's hoping to get drafted this year. What advice is the longtime pro giving his boy?

The NBA champs have taken their celebration to Florida ... with Jayson Tatum and his Boston Celtics teammates arriving at a fancy hotel in Miami on Tuesday -- and, of course, the Larry O'Brien Trophy came along for the fun!!

TMZ Sports has obtained video of the superstar hooper all smiles as he cradled the hardware ... showing him hopping off a team bus and into the building.

It was no secret the victors were heading for the Sunshine State -- they had their travel plans etched on a whiteboard in the locker room as they partied their faces off after beating the Dallas Mavericks on Monday.

Doris Burke poked fun at the nationwide Caitlin Clark obsession during Game 5 of the NBA Finals on Monday ... cracking a joke about the narrative surrounding the WNBA superstar's treatment on the court.

The ESPN talent name-dropped the Indiana Fever hooper following a hard foul in the second quarter of the Celtics' series-clinching win over the Mavericks ... when P.J. Washington wrapped his arms around Kristaps Porzingis and dragged him to the hardwood.

Burke was quick to react with a witty comment ... saying, "If that were Caitlin Clark, it might spark a debate for a week."

The Boston Celtics and Dallas Mavericks weren't the only ones going head to head in the NBA finals ... a bunch of Celtics fans got into an amateur boxing match at a game 4 watch party.

Friday night's brawl broke out between two men seated near each other in the crowd at TD Garden arena in Beantown ... where Celtics fans were having a viewing party of the on-court action taking place inside American Airlines Stadium in Dallas.

Check out the vid ... the younger dude was standing over the older guy and using his head as a punching bag. Several bystanders and a security guard tried to pull the aggressor off the old man as he cowered on cement stairs.
