MMA World Series of Fighting has lost one of its biggest bouts for this Saturday’s WSOF 22 event in Las Vegas, as Thiago Silva has been denied a license to compete by the Nevada Athletic Commission.

Silva, who lost his WSOF debut back in March, was to face Mike “MAK” Kyle in a light heavyweight bout in Saturday’s show.  He will be replaced by Clifford Starks.

It’s the latest in a series of controversies for the Brazil-born, Florida-based Silva, who was released by the UFC last year due to a domestic violence controversy — as described here at Caged Insider.

Silva had already been suspended by Nevada Athletic Commission officials due to a falsified urine sample he produced after a 2011 bout. He will need to appear before the Commission to argue his case before being re-instated.

“We hope that Thiago will take the steps necessary to be in compliance with the state athletic commission so that he can make a quick return to action,” said WSOF President Ray Sefo in a statement to media this morning. “In the meantime, we appreciate Clifford Starks’ willingness to take the fight against Mike Kyle on just a few days’ notice, and look forward to having him compete for us again after putting on a great show in the WSOF cage in March.”

Clifford Starks is 11-2 as a professional and currently enjoying a three-fight win streak, including a submission victory over Jake Heun at WSOF 19 in March. A former wrestler for Arizona State University, Starks has also competed for the UFC and Bellator.
