Middleweights Demian Maia and Dan Miller will return to the Octagon in February, squaring off in a featured contest at UFC 110 on February 6 in Las Vegas. Maia improved to 11-0 with five-straight UFC victories before suffering a first-round knockout at the hands of Nate Marquardt in August, while Miller had won three-straight before a May loss to Chael Sonnen.

An infection has forced middleweight Dan Miller to withdraw from his scheduled matchup against CB Dollaway at UFC Fight Night 19 on September 16 in Oklahoma City. According to MMA Madness, which first reported the injury on Tuesday, newcomer Jay Silva has agreed to replace Miller and make his Octagon debut against Dollaway on less than two-weeks notice.

Wilson Gouviea’s recent-withdrawal from a scheduled UFC 102 fight against Ed Herman has caused the UFC to shuffle several upcoming matchups, as Herman will now fight Aaron Simpson at the August 28 event, while Dan Miller, who was to fight Simpson at UFC Fight Night 19, will instead meet CB Dollaway on the September 16 card.

Middleweight Wilson Gouveia has withdrawn from his UFC 102 matchup against Ed Herman after suffering a back injury that will sideline him until at least October.

MMA News first reported the injury on Friday just days after Herman was tapped to replace an injured James Irvin and take on Gouveia at the August 29 event in Portland.

A middleweight matchup between Dan Miller and Aaron Simpson, which was first reported early last month, is now back on for UFC Fight Night 19 after a fight between Simpson and Ed Herman was scratched from the card when Herman was tapped to replace an injured Jame Irvin at UFC 102 earlier this week.

13 fighters from the 11-bout UFC 100 card, which took place last Saturday and the Mandalay Events Center in Las Vegas, were tested by the Nevada State Athletic Commission for steroids and drugs of abuse and all of the tests were negative according to NSAC executive director Keith Kizer, who confirmed the results to MMAFrenzy.com on Friday.

The UFC 100 fighters which were tested were Frank Mir, Brock Lesnar, Georges St-Pierre, Thiago Alves, Shannon Gugerty, Jon Fitch, Dan Henderson, Yoshihiro Akiyama, Mark Coleman, Tom Lawlor, Jon Jones, Dong Hyun Kim, and Dan Miller.

Middleweights Dan Miller and Aaron Simpson are likely to fight at UFC Fight Night 19 on September 16 in Oklahoma City, according to Simpson, who recently announced the matchup on Facebook (but later said nothing was official yet).

UFC Fight Night 19 is also set to feature Gray Maynard vs. Roger Huerta, with tickets for the Spike-televised event set to go on sale on July 9.

The Nevada State Athletic Commission has issued medical suspensions to nine fighters who fought at UFC 98 on May 23 in Las Vegas. Main event loser Rashad Evans, who suffered a second-round knockout to Lyoto Machida, is suspended until July 23rd for precautionary reasons.

Headliners Rashad Evans and Lyoto Machida and co-main event fighters Matt Hughes and Matt Serra were the top earners at UFC 98 on Saturday in Las Vegas. Evans, the former UFC light heavyweight champion who was defeated via second-round knockout by Machida, earned $200,000 for the bout. Machida received $140,000 for his main event victory.

Lyoto Machida became the new UFC light heavyweight champion on Saturday in Las Vegas, taking out title-holder Rashad Evans with a flurry of punches in the second round of their UFC 98 headliner to capture the 205-pound belt. Matt Hughes, Drew McFedries, Chael Sonnen, and Frankie Edgar also picked up main card victories.

All 22 fighters, including UFC light heavyweight champion Rashad Evans and challenger Lyoto Machida, rivals Matt Hughes and Matt Serra, and late-replacement Mike Pyle, successfully made weight on Friday in Las Vegas for UFC 98. The event's official weigh-in results are available after the jump...

Hours after being unofficially confirmed as the replacement for an injured Yushin Okami, Ed Herman has apparently been bumped from the UFC 98 card for undisclosed reasons and replaced by Chael Sonnen, who will now meet Dan Miller on May 23rd in Las Vegas.

Ed Herman has been selected to replace an injured Yushin Okami against Dan Miller at UFC 98 on May 23rd in Las Vegas. The news, which comes via MMA Weekly, is a bit disappointing considering the UFC promised an "awesome replacement challenger".

The UFC announced on Thursday afternoon via Twitter that Yushin Okami has been forced out of his UFC 98 bout against Dan Miller after suffering a torn ligament. According to the message, an "awesome replacement challenger" will be announced as soon as possible.

Just one day after officially announcing UFC 98: Lesnar vs. Mir 2, the UFC today confirmed the majority of the event's lineup, adding Matt Hughes vs. Matt Serra, Dan Miller vs. Yushin Okami, and Sean Sherk vs. Frankie Edgar to the UFC 98 main card.
