Ronda Rousey's former training partner, Kayla Harrison -- who's still friends with the UFC superstar -- says Ronda is surrounded by some people who don't have her best interests at heart ... and she needs to ditch them ASAP.

FYI, Kayla is a 2-time Olympic gold medalist in judo -- and trained with Ronda on a daily basis for years. They're still friends and spoke on the phone just a few weeks ago.

Harrison says Ronda seemed to be in a great mental space before the fight and "expected her to come back with a vengeance."

But the one thing that concerns Kayla ... she believes there are people who have latched on to the UFC star "that maybe don't have Ronda's best interest at heart."

She didn't call anyone out by name -- but wants to remind Ronda that she still has TRUE FRIENDS and family members out there who care about her ... and those are the people she should surround herself with.

By the way, Harrison also tells TMZ Sports she's one step closer to fighting MMA ... and got the itch while announcing at the World Series of Fighting this past weekend.

Ronda Rousey's coach is trying his best to stay positive in the wake of her crushing defeat at UFC 207 ... and tells TMZ Sports he's tuning out the hate.

Cody "No Love" Garbrandt says he was MERCIFUL to Dominick Cruz -- claiming he could've knocked him out "multiple times" at UFC 207 ... but was having too much fun toying with the guy.

Cody joined the guys on the "TMZ Sports" TV show (airs Tuesday night on FS1) -- and said he could pinpoint the moment he knew he had the fight locked ... but carried Cruz to the 5th round "for fun."

Garbrandt says he had such a great time beating Cruz he wants a rematch -- and says next time, Cruz won't make it past the 2nd.

Ronda Rousey's biggest sponsor is reaffirming its support for the UFC star ... even after her big loss at UFC 207 ... with Reebok telling TMZ Sports the company "stands with Ronda 100%."

Ronda signed an individual deal with the athletic wear company in 2014 -- when she was at the top of her game. Now, after 2 devastating losses in a row, we asked if she was in danger of being dropped.

Ronda Rousey has broken her silence after that brutal loss at UFC 207 ... and it's clear she's considering retiring from the sport.

Ronda issued a statement to ESPN, saying in part "I need to take some time to reflect and think about the future" ... This after getting knocked out by Amanda Nunes just 48 seconds into the fight.

She goes on to say her entire focus this year has been pulling off a victory next time she got in the ring. She's clearly very shaken ... adding, "sometimes even when you prepare and give everything you have and want something so badly -- it doesn't work out how you planned."

Ronda beelined it out of the arena Friday night without talking to anyone, except a few fans.

As we reported, even her mom would like to see her hang up her gloves for good.

Pretty cool post-fight conversation with UFC superstars Tyron Woodley and Demetrious Johnson -- who both seem to think Ronda Rousey should NOT retire ... despite the ass whoopin'.

Check out the clip ... it's interesting to hear what accomplished MMA stars like TW and DJ think about Ronda and how she should handle her career going forward. '

Michael Irvin was FIRED THE HELL UP on his way out of UFC 207 ... and compared the RUSH he got from watching the fights to the same feeling as winning a Super Bowl!!

"I haven't got that feeling since I scored touchdowns in the Super Bowl ... and I've won a LOT of Super Bowls!!!!"

Amanda Nunes was not into fancy champagne celebrations after kicking Ronda Rousey's ass in UFC 207 ... all she wanted was Bud Light!

We got Amanda beelining it for Wolfgang Puck's Bar & Grill in the MGM Grand after her 48 second KO and she was a woman determined to celebrate her way.

Ronda Rousey wears defeat on her sleeve ... and this photo says it all.

We spotted her late Friday leaving the MGM Grand after getting knocked out in 48 seconds by Amanda Nunes.

A fan approached to comfort her, and you feel the despair.

Newly crowned UFC bantamweight champ Cody Garbrandt says his win against Dominick Cruz was the best 25 minutes of his life.

We got Cody in the lobby of the MGM Grand after winning the belt, and his comments about his relationship with Dominick Cruz is super interesting ... given their trash talk in and out of the octagon.

Speaking of Cruz ... we also got him at the MGM in Vegas, and he's handling the loss like a champ. The decision didn't go his way, but it didn't stop him from partying.

Ronda Rousey's mom didn't mince words after her daughter's UFC 207 disastrous loss ... her kid needs to hang it up.

We got AnnMaria De Mars at the MGM after she watched Amanda Nunes knock her daughter out 48 seconds into the first round.

AnnMaria sounds like she never wanted Ronda to fight ... ever, and throws shade on those who do.

And talk about beef ... AnnMaria cannot hide her contempt for Ronda's coach.

Warning to Cody Garbrandt ... YOU HAVE AN ASS KICKING COMING ... at least that's what MMA star Phil Davis thinks ... telling TMZ Sports his training partner, Dominick Cruz, is gonna slap Cody around.

Garbrandt and Cruz are set to face off at UFC 207 ... and the two men have been throwing verbal darts at each other since the bout was announced ... calling each other every name in the book.

We got Davis out at LAX, and the Bellator star delivers bad news to Team Garbrandt ... saying Cody has a ZERO PERCENT chance to beat Cruz, who he says has been DOMINATING during training.

Ronda Rousey just faced off with Amanda Nunes at the UFC 207 weigh-ins ... and it was INTENSE!

Nunes -- nicknamed "The Lioness" -- showed up in lion mask and looked VERY easy going about the whole fight.

Ronda flashed a smile for a quick second before returning to angry mode.

But the big story was the confrontation between Cody Garbrandt and Dominick Cruz -- when they yelled and pushed at each other during the showdown.

UFC stud Louis Smolka says he ain't backing out of his UFC 207 fight with Ray Borg ... even though his opponent is more than 3 POUNDS overweight.

It's a big deal ... especially between two flyweight fighters (125 pounders) ... but Smolka says he's a fighter and fighters fight.

The silver lining for Smolka ... he says he finally gets to be the good guy for a change.

Ronda Rousey looks READY TO GO ... showing off her ripped physique at the official UFC 207 weigh-in Thursday morning ... where she hit the media with the silent treatment.

Ronda didn't say a single word as she hit the scale before her championship fight with Amanda Nunes ... and weighed in a perfect 135 pounds.

She looks ripped. She looks strong. She looks ready.

UFC rising star Cody "No Love" Garbrandt says he's lucky to be alive after being stabbed in a crazy bar fight before his UFC career ... saying he was forced to fight after a guy pulled a knife on him.

Garbrandt was telling Champions.co why he's tough enough to face Dominick Cruz at UFC 207 on Friday -- and recalled the bar fight he was wrangled into in a back country bar in Ohio a few years ago.

You gotta hear Cody tell the story ... it's crazy.
