If you recall, Mein became the first man ever to finish Dan Miller (via first round TKO) at the event — a feat made all the more impressive when you realize just what kind of killers Miller has faced over his career, along with the fact that he had Mein in a tight armbar just moments before being finished. And being that Mein was able to come away from the fight practically untouched, it was announced earlier today that Young Gun will now being making a quick turnaround against Matt Brown at UFC on FOX 7, as Brown’s original opponent, Dan Hardy, has been forced to withdraw from the fight due to injury. Barns, they will be burned. After suffering a horrific 1-4 stretch between 2010-2011, Brown was able to completely (and somewhat unexpectedly) turn his career around in 2012, putting together four straight victories including a KO win over Mike Swick at UFC on FOX 5 last December. Mein, on the other hand, has tasted victory in 9 of his last 10 performances, leaving the likes of Josh Burkman, Joe Riggs, and Evangelista Santos in his wake. So, Potato Nation, do you have Mein by murder or Brown by…murder? [UPDATE]  Turns out Hardy wasn’t injured; he was not given medical clearance for the fight due to a pre-existing condition. Hardy gives us the details via his Twitter after the jump.
