Back in 2013 after a run in the UFC that included challenging then-champion Georges St-Pierre, Fitch signed with the World Series of Fighting. He captured the vacant WSOF title in 2016 with a decision win over Joao Zeferino.

The WSOF has since re-branded itself to become the Professional Fighters League, as they plan to hold season-long tournaments. Fitch, who defended his title vs. Jake Shields and Brian Foster, posted a message on his official YouTube channel indicating he is now a free agent.

“As of (last Friday), I am officially a free agent,” Fitch said. “I’m in talks with Scott Coker and Bellator right now. Hopefully, we’ll work something out by the end of the week.”

Fitch, who turns 40 years old later this month, turned pro in 2002 following a four-year run with Purdue University on the wrestling mats. He was a walk-on at Purdue, going on to become a team captain and winning 45 matches.

He began his career competing against future fellow UFC fighter Mike Pyle, suffering a submission loss. Fitch signed with the UFC in 2005 and won eight consecutive bouts to earn himself a shot against St-Pierre in 2008 for the title.

Following the loss to GSP, Fitch won five consecutive bouts before a draw with BJ Penn and a knockout loss to Johny Hendricks in 2011.

Fitch went 6-2 over eight fights with the WSOF and PFL, defeating Foster, Shields, Yushin Okami and Dennis Hallman around losses to Josh Burkman and Rousimar Palhares via submission.

The Bellator welterweight division currently features champion Rory MacDonald, former two-time champion Douglas Lima, ex-titleholder Andrey Koreshkov, Michael Page, Kevin “Baby Slice” Ferguson Jr., Fernando Gonzalez, Brennan Ward, Ryan Couture, Joey Davis and Josh Koscheck.
