Andrei Arlovski is a former UFC Heavyweight Champion, sure it was from an era that is not well known for UFC's Heavyweight division, but to question if Arlovski was "legit" or not is a bit, well, ridiculous. He reigned supreme over UFC's division while Fedor reigned over Japan. Sergei Kharitonov has some legitimate wins from PRIDE and has competed in K-1 over the past few years, so a battle between Kharitonov vs. Arlovski is a fight that we've been waiting to see for a while, and it's happening in Strikeforce.
Arlovski comes in staring down the barrel of a long, three-fight losing streak (Fedor, Rogers, Silva), while Kharitonov hasn't faced top competition at Heavyweight in the past few years and won. Both men have a lot to prove on the world level here tonight, and this could make or break a career. Arlovski starts off strong and uses his movement and hands, but Kharitonov was patient and waited for his moment and struck, hard, swarming on Arlovski and not stopping until Arlovski was on the ground, knocked out cold.
This is Arlovski's fourth KO loss in a row, and one has to believe that he'll be dejected by this and there will be a lot of questions about his career.
