Andrei Arlovski just beat the #4 heavyweight title contender, do I dare say, Arlovski is “in the mix”

Crowd in Brazil seems stunned. I’d say Arlovski’s most important win since he beat Roy Nelson in 2008 (controversy aside).

Andrei Arlovski is relevant in the UFC heavyweight division in 2014. Who knew?

Arlovski just put Greg Jackson on his shoulder and took a victory lap around the octagon. He is, how you say, happy.
