"This better be inaccurate" - Kamaru Usman's alleged "something popped" comment at UFC 294 open workouts has fans worried

Kamaru Usman has fans worried after a clip from his open workouts showed him telling Justin Gaethje that something appeared to be wrong.

The former welterweight champion entertained fans earlier today as he took part in the open workouts ahead of his middleweight bout against Khamzat Chimaev this Saturday at UFC 294. Everything seemed fine, but after 'The Nigerian Nightmare' executed a routine takedown on the 'BMF' title holder, he noted that he felt something.

Here's the interaction:

Justin Gaethje: Are you alright?

Kamaru Usman: Something popped.

Kamaru Usman concluded his open workout after getting back to his feet and acknowledging the fans in attendance. Fans commented on Bloody Elbow's tweet by expressing their concern for Saturday's co-main event. They hoped that the former welterweight champion didn't suffer an injury during the open workout, writing:
