WATCH: Did Justin Gaethje just injure Kamaru Usman at UFC 294 open workouts? [UPDATED]

UFC open workouts are rare these days but they hosted one for UFC 294 on Wednesday and it might be the last time they do it.

While working out with BMF champion Justin Gaethje, it appears that former welterweight champion Kamaru Usman might have injured himself.

After a toss you can hear Gaethje quitely ask if Usman is ok and he whispers "something just popped.”

They exited the mats shortly after.

After the video began making its rounds on social media, Gaethje took to Twitter in an attempt to change the narrative.

"He said I’m good or something like that. I thought he hit his head on the mat. I asked him if he hit his head in this clip when we got up and he said no," Gaethje wrote.

He also said that Usman said, "He actually said I’m gunna go with cosmo to be exact." He was referring to Cosmo Alexander who he started hitting pads with shortly after the video was taken.

After Gaethje's comments did nothing to dispel the rumors, Usman himself took to Twitter to explain what did and didn't happen.

“Oh my God. People believe anything you put on this internet. Anything – any f*cking thing," Usman said. “Guys, this is crazy – yesterday, seeing the tweet (about me being injured),” Usman said. “It just goes to show how crazy people just jump on news and media and, ‘Oh, that must be true. That person said that! That person said that!’ Whoever started it – whoever said they heard or saw: How could you have possibly heard what I said when it’s me and Justin, on a stage, in front of thousands of people in a mall? Were you next to us where you heard what I was saying?"

He continued on saying, “How stupid. Just dumb. If my knee was hurt, why would I get up and (continue) hitting mitts? Oh my God. People believe anything you put on this internet. Anything – any f*cking thing. Whoever that was, stop it. Stop with the clickbait. (I) did not say that. Clearly, I’m fine. Dummies: I’m fine.”

It's worth noting that Usman might be covering his injury in order to not be pulled from the fight or tip off his opponent,

Usman is stepping in to replace Paulo Costa who was forced out if his fight with Khamzat Chimaev due to a very serious infection on his elbow.

Ahead of their match-up Usman sang the praises of Chimaev.

“I think he’s as advertised. He’s very tough, he’s big, he could strike, he could wrestle, he can grapple, he can do it all. So can I. I think he’s as advertised, but you don’t know until you know," he said at media day. “Ignorance is bliss sometimes. I give him all the props in the world. He’s definitely done everything he needed to do with what he’s been presented with, but iPhone Pros don’t fit in certain pockets. You might need just a regular iPhone. They both take good pictures, and they both work just fine.”

At press time there's been no confirmation of Usman's condition but we'll be following it carefully and update when any new information is learned.
