"I'm not sure when I'll come back event because I'm still with a shoulder injury, another injury arouse recently on my lower back, so I'm getting treatment"

Ultimate Fighting Championship (UFC) Middleweight Champion Anderson Silva, who is currently on the sidelines with a shoulder injury, tells Brazilian television show "Bom Dia Brasil" (via Tatame.com) that he has suffered yet another setback on his road to a return to the Octagon. This time, it's "The Spider's" back that seems to be giving him trouble. Though Silva's past injuries may have been questioned in the past, UFC President Dana White reiterated that his shoulder injury is legit as he was examined by UFC doctors. The 36-year-old mixed martial artist (MMA) has not seen action since defeating Yushin Okami at UFC 134 on Aug. 27, 2011 in Rio de Janeiro, Brazil. The Brazilian is expected to defend his 185-pound strap against the winner of the higly anticipated scrap pitting Chael Sonnen vs. Mark Munoz, which will take place on Jan. 28, 2012 at UFC on Fox 2 in Chicago, Illinois. Just yesterday, it was reported that Kenny Florian's nagging back problems may force him into early retirement but there's no word on exactly how serious Silva's injury is and how much longer the middleweight kingpin will be riding the pine. Let's hope it's not nearly as devastating as "Ken Flo's" prognosis, yeah?
