- James Irvin officially became the most cursed MMA fighter in history.

- Josh Barnett’s latest steroid bust, which single-handedly destroyed Affliction’s MMA promotion, actually saved the sport of mixed martial arts.

- Speaking of ‘roids, BJ Penn is pretty sure that Georges St. Pierre uses them, because how else would you explain his physique? You know, other than genetics and hard work…

- Sengoku’s featherweight grand prix finals turned into a clusterbang of injuries and racism.

- Former UFC heavyweight champ Andrei Arlovski may have attempted suicide after two straight knockout losses.
