2011 is proving to be a bad year for George Sotiropoulos.
Coming out of 2010, George was riding a seven fight win streak in the UFC's lightweight division. Many fans were toting him as the next big threat to the lightweight belt.
However, Sotiropoulos suffered a set back when he dropped a unanimous decision to rising lightweight contender Dennis Siver. It was a particularly tough loss for George because it came in his homeland of Australia.
At UFC 132, the Australian lightweight stand out was hoping to get back to his winning ways with a victory of Rafael Dos Anjos.
Unfortunately, things didn't go quite as George might have liked.
Sotiropoulos and Dos Anjos got into a wild exchange early in the first round and Rafael connected with a hugely momentous hay maker.
The punch landed right on George's chin and his legs gave out.
The referee saw Sotiropoulos legs give out and his head hit the canvas and decided to stop the fight.
This is a huge win for Rafael who came into this fight off of a tough loss to Clay Guida.
Dos Anjos was actually doing very well in his fight with Guida, but sustained an injury to his jaw that left him unable to continue.
The lightweight division is already arguably the most stacked in the UFC, but there might be another title contender emerging in the form of Rafael Dos Anjos.
Expect Rafael to be fighting a big name in the lightweight division next time you see him inside the Octagon.
