Following losses in three of his last four fights, the UFC has released light heavyweight Jake O’Brien. “Irish” won his first three UFC fights to push his record to 10-0, but back-to-back losses to Andrei Arlovski and Cain Velasquez, as well as a loss to Jon Jones in his most-recent bout in July resulted in him being the latest cut from the UFC’s roster.

Frank Mir, Georges St-Pierre, Thiago Alves, and Michael Bisping were among the 13 fighters issued medical suspensions by the Nevada State Athletic Commission on Monday following their bouts on Saturday at UFC 100.

Mir, who suffered a second-round knockout to Brock Lesnar in the UFC 100 main event, must sit out until September 10 following the loss, while St-Pierre, who defeated Alves by unanimous decision in the co-headliner, could be suspended until January 8 due to a groin injury sustained in the victory.

All 22 fighters scheduled to compete tomorrow at UFC 100 successfully made weight on Friday at the event’s official weigh-ins, which were held at the Mandalay Bay Events Center in Las Vegas, the same venue which hosts Saturday’s pay-per-view event.

UFC heavyweight champion Brock Lesnar weighed-in exactly at the 265-pound heavyweight limit, while interim title-holder Frank Mir came in 20-pounds lighter at 245. UFC welterweight champion Georges St-Pierre (170) and challenger Thiago Alves (170) as well as TUF 9 coaches Dan Henderson (185) and Michael Bisping (186) also made weight without issue.

The UFC on Thursday officially announced five more bouts for its historic UFC 100 event. Added to the lineup were Yoshihiro Akiyama vs. Alan Belcher, Jon Jones vs. Jake O'Brien, Dong Hyun Kim vs. Jonathan Goulet, CB Dollaway vs. Tom Lawlor, and Matt Grice vs. Shannon Gugerty.

Fedor Emelianenko vs. Tim Sylvia
Emelianenko via submission, round 3.
To me this is a pretty simple pick. Fedor will definitely have respect for Sylvia’s punching power, and will likely only stand and trade with the much taller opponent for a short while. Fedor will shoot for a takedown here and there but will probably get [...]
