Former UFC champ Matt Serra has seen the footage of T.J. Dillashaw being knocked out by Cody Garbrandt.

The hottest rivalry in mixed martial arts this summer is the feud between former Team Alpha Male teammates Cody Garbrandt and T.J. Dillashaw.

Garbrant, the current UFC bantamweight champion, and former champ in Dillashaw, can be seen coaching opposite one another weekly on the FS1 hit television series, The Ultimate Fighter.

A fight between the two is set to take place later this summer but the rivalry leading up to the title fight has been building as the days go by.

Garbrandt has long claimed that he has a video of him knocking out Dillashaw when the two previously trained together. Garbrandt went as far as to say he would shop around for the highest bidder and donate the money to charity.

Dillashaw was then on UFC Unfiltered earlier this week where he addressed the video that Garbrandt supposedly has.

“Tell him, ‘Go for it, release it.’ Cause I for one don’t believe it. It’s something like, we put this time, and tears, and sweat into the gym, and he’s got this one clip of him doing good? What about the 70 percent of the time when I was doing awesome that Buchholz has footage of? But you know what, I could care less what happened then,” Dillashaw said. “I get to make on pay-per-view, some film of me beating Cody’s ass, and I’m going to make a lot more than selling it to TMZ.

“They can do whatever they want with the practice room, cause we all know how it went down. I could care less, release the footage. The charity should be something with kids without fathers so they don’t grow up to act like Cody.”

Matt Serra and Jim Norton, hosts of the UFC Unfiltered Podcast took it a step further and had new Team Alpha Male head coach Justin Buchholz call into the show later to address the video.

“It all started with T.J. saying he used to beat the s**t out of (Urijah) Faber for years or something you know? And then Cody tweeted ‘If you wanna talk about sparring, why don’t you talk about the time I knocked you out?’ And then from there, T.J. was like ‘no that’s not true, you didn’t knock me out.’ And then Cody hit me up and was like, ‘Hey, do you have that tape?’ And I was like, ‘Yes.’ And I looked on my files of sparring that I have. I have hours and hours of me sparring,” Bucholz said. “I used to set up a Go-Pro (camera) and have myself sparring. So I was sparring one time in the room, and it was T.J. and Cody, and this was the said tape. I actually show it to Matt (Serra).”

“I seen it,” Serra said in a comical voice. “I wasn’t going to say anything, but you did show it to me. I wasn’t going to bring it up.”

Will the video be released?

“Just like you said, I think it would be completely wrong to release that tape,” Buchholz said. “T.J. was a teammate at the time. Cody was a teammate at the time. I was filming my sparring. They happened to come into the round and the incident happened.

“That’s where it started, Cody was sticking up for Urijah. I think it wrong to release the tape, but at this point, no, I can kind of do whatever I want cause morally, T.J. says ‘You don’t have a tape. You guys are lying. Release the tape if you have it.’ So at this point, he said I can do it. So now it’s just kind of my choice if I want to do it and I just don’t really feel like releasing it. Yeah maybe, we’ll see what happens. We’re in the promotion business and this guy told me to release it.”
