FanHouse Tom Lawlor

In his first fight since dispelling the EliteXC myth of Kimbo Slice, Seth Petruzelli returns Saturday against IFL veteran Chris Baten at Art of Fighting 4 in Tampa, Fla.

Last October, Petruzelli (10-4) became an unlikely hot topic when he accepted a main event fight against Slice on a few hours notice and proceeded to stop the EliteXC main draw in 14 seconds. Although the event on CBS turned out to be the third most watched MMA card ever, Slice's loss in credibility and Petruzelli's controversial comments following the fight heavily contributed to the company's closure within the end of the month.

LAS VEGAS -- The UFC fell just shy of its best-ever Nevada gate, with 11,000 fans spending $5.1 million at the box office in ticket sales for UFC 100 at the Mandalay Bay Events Center.

LAS VEGAS -- This is the UFC 100 live blog for undercard fights featuring Matt Grice vs. Shannon Gugerty, Tom Lawlor vs. CB Dollaway, T.J. Grant vs. Dong-Hyun Kim and Jim Miller vs. Mac Danzig. The live blog is below.

LAS VEGAS -- Only one thing stands between Frank Mir and one of the most unlikely comebacks in MMA history. Unfortunately for Mir, that one thing is 6-foot-4, 265 pounds (before rehydrating) and has a boulder rather than a chip on his shoulder.

With revenge on his mind, Brock Lesnar will attempt to stop Mir from becoming a two-time UFC champion at UFC 100 and complete a comeback from a career-threatening injury caused from a motorcycle crash.

The two heavyweights weighed in at the Mandalay Bay Events Center, and to no one's surprise, Lesnar outweighed Mir, 265 to 245. Mir looked preternaturally calm during his time on stage, laughing at Lesnar's pose on the scale and showing none of the menace that many fighters often display when facing their opponent for the last time before it really counts.
