Thiago Silva pulled from WSOF 22 after NSAC denies license to fight Mike Kyle

Take this cup, step into the stall, and hand it back to the official when you're done. Or, if you're Thiago Silva, don't take the cup, don't turn in the sample, and (eventually) get disqualified from competing.

That's the breaking news right now for the World Series of Fighting (WSOF) 22: "Palhares vs. Shields" event, scheduled to take place this Sat. (Aug. 1) at Planet Hollywood Casino & Resort in Las Vegas, Nevada. A light heavyweight contest between Silva and Mike Kyle was set to be one of the featured bouts on NBC Sports Network.

"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 today's release. "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."

The embattled Silva -- who signed with WSOF after getting his walking papers from UFC -- was popped for phony urine back in 2011 (more on that here) and was required to square that incident away by way of NSAC hearing before returning to action.
