No. 14-ranked heavyweight in the UFC, Valter Walker, has found himself in a world of trouble. Why? Well, ‘The Clean Monster’ appears to have been arrested in Miami on Thursday. And his arrest may have jeopardised his special grappling match on Friday at Karate Combat 59 in Miami with Zion Clark, a man born with no legs due to caudal regression. 

Interestingly, the news of Walker’s arrest comes after the pair got into a scuffle during their final face-off on Thursday afternoon. The Brazilian heavyweight’s Instagram handle shared the update with fans. “We inform you that the athlete Valter Walker was detained by Miami authorities this Thursday (02/12) at 2:45 PM Miami time,” Walker’s Instagram post read.

It also included a couple of pictures—the first one showed Valter Walker getting cuffed near a police station. And the second one showed he was sitting in a detention area with his hands restrained behind his back. “Consequently, his fight scheduled for tomorrow remains pending his release from custody,” the post added, hinting the fight might not happen. 

“We are currently seeking Miami-based lawyers for immediate legal support,” the post continued. “If you are or know a professional in the area, please contact us urgently via Direct Message (DM).” However, it’s currently unclear what Walker is being charged with or the reason behind his arrest on Thursday. 

Notably, though, Walker had mocked Clark during their face-off prior to his arrest on Thursday, which prompted Clark to grab the Brazilian and pull him to the ground. The American then locked Walker in a front headlock before delivering a few punches to his body. Security quickly stepped in and separated the pair.

Walker, while restrained, tried to kick the American, but failed. “Everybody thinks I’m gonna take it easy on him because he has no legs. I will smash this motherf—,” Walker said following the incident. Regardless, Walker’s Instagram account has since provided further updates about the Brazilian’s arrest and whether he will be able to fight Clark. 

UFC fighter Valter Walker is expected to be released soon

According to a follow-up post on Walker’s Instagram, he is currently held at the Miami-Dade County Pretrial Detention Center. “We hereby inform that UFC athlete Valter Walker is currently in custody at the Pretrial Detention Center,” the ‘official statement’ read. “His release is scheduled for tomorrow morning, following the payment of bail as determined by the competent authorities.”

The bail amount wasn’t revealed in the post, but it claimed a “professional colleague” will be providing the funds for Walker’s release on bail. “Valter Walker’s management and legal team are closely monitoring all legal proceedings to ensure his prompt release and full compliance with judicial requirements,” the statement concluded. Notably, after Friday’s match, Valter Walker is set to face UFC veteran Marcin Tybura. 

The pair will face each other in a heavyweight bout on March 28, 2026, at UFC Seattle. 

As more details emerge about Valter Walker’s arrest, the specific reason behind it will likely be revealed to the public. For now, however, it remains a matter of speculation. What do you think could have led to his arrest in Miami?
