Brock Lesnar, the UFC heavyweight champion, announced Wednesday that he expects to be back in the Octagon this summer, putting to rest three months of rumors and speculation about his future.

Lesnar made the claim on ESPN's SportsCenter in the morning. He was suffering from diverticulitis, an intestinal disease, and had lost 40 pounds, making him appear human in comparison to the 265-pound brickhouse we're used to seeing.

Lesnar was supposed to defend his title against Shane Carwin at UFC 106 last November, but that was pushed back to UFC 108 earlier this month before being canceled. Carwin will fight former champ Frank Mir for the interim heavyweight title at UFC 111 on March 27 in Newark, N.J. (Also on that card, Georges St-Pierre defends his welterweight belt against Dan Hardy.)

It's probably safe to assume that Lesnar will face the Mir-Carwin winner in his return bout.

Lesnar is already the biggest pay-per-view draw in MMA, and that return bout will only make him bigger.

Fightin' Words will have more on Lesnar later tonight, but right now, we're at Renzo Gracie's in NYC with Matt Serra, Dan Miller, Philippe Nover and Renzo.
