"You can't grow muscles on your chin."

That's according to "The Mad Greek," Christos Piliafas, who takes on the former world's strongest man, Mariusz Pudzianowski, at the Konfrontacja Sztuk Walki (KSW) 20 event on Sept. 15, 2012 from the Ergo Arena in Gdansk, Poland.

That's not all.

Former Ultimate Fighting Championship (UFC) Light Heavyweight Houston Alexander gets back in action opposite Jan Blachowicz. "The Assassin" headlines the European mixed martial arts (MMA) card and hopes to snap a two-fight losing streak against the hometown hero.

Looking to follow suit is "Geronimo."

Former K-1 star Jerome Le Banner is also coming off a loss in his last foray into MMA, dropping a unanimous decision to Satoshi Ishii in late 2010. Can the aging striker get things turned around by overcoming Marcin Rosalski? "Rozal" needs a win to avoid dropping into an 0-3 hole.

Good times.
