After badly missing weight for World Series of Fighting 4 this past weekend and ultimately being cut from the promotion, Lew Polley will be back in action this week – as a heavyweight.

Polley (12-4) didn’t officially weigh in for his WSOF 4 bout with Hans Stringer, but an event source told MMAjunkie.com (www.mmajunkie.com) he tipped the scale at 237 pounds. He’s now replaced James Wilson (2-0), whom RFA officials said broke his hand, and meets NCAA Division I national wrestling champion and Olympian Steve Mocco (2-0) at Friday’s RFA 9 event.

RFA 9 takes place at StubHub Center in Los Angeles, and the main card, including Mocco vs. Polley, airs on AXS TV.

Mocco, who wrestled at the University of Iowa and Oklahoma State University before making the 2008 Olympic team, ultimately turned his attention to MMA in 2012 after hooking on with American Top Team. He made his pro debut in late 2012 and has picked up a pair of submission wins, over Tyler Perry and Rashad Brooks.

He now takes on Polley, a fellow Division I wrestler who represents Mocco’s most experienced opponent to date. Polley, who served as a coach on “The Ultimate Fighter 13,” has fought for organizations such as the IFL and Bellator. Most recently, he defeated former UFC fighter Carmelo Marrero in October.

“Mocco’s a tough guy with great credentials coming into the sport,” Polley stated. “It’s a huge privilege to be fighting someone of his caliber. He is incredibly strong and mentally tough. I think we’re going to see a chess match that will give the fans a glimpse of our future and where our careers are headed. I plan on taking his momentum at RFA 9.”

The latest RFA 9 card now includes:

MAIN CARD (AXS TV, 10 p.m. ET)

PRELIMINARY CARD (Untelevised, 8 p.m. ET)
