After middleweight contender Yushin Okami was forced to withdraw from his upcoming match-up with Dan Miller earlier today due to a torn ligament, many reports were circulating that Ed Herman had agreed to fill Okami’s shoes, but now it appears as yet another opponent has been tabbed to face Miller.

Chael Sonnen has recently agreed to the match-up with Miller that will take place at UFC 98 according to multiple reports.

UFC 98 is scheduled for May 23 and will take place at the MGM Grand Garden Arena in Las Vegas.

Sonnen is an NCAA All-American and a two time National Champion wrestler and a veteran of the Pancrase, Bodog Fight, WEC and UFC organizations. He was recently submitted in the first round by Demian Maiain his return to the UFC in February. Sonnen was previously espected to face off with Wilson Gouveia at UFC 102 but opted to forfeit that bout in favor of the UFC 98 match-up with Miller.

Miller’s first and only professional loss came to Mike Massenzio in the form of a split decision over three years ago. He has established himself as a legitimate threat in the UFC’s middleweight division with impressive victories over the likes of Rob Kimmons, Matt Horwich and most recently Jake Rosholt in February. He is the brother of UFC lightweight challenger Jim Miller.

UFC 98 is set to be headlined by a light heavyweight championship match-up between Rashad Evans and Lyoto Machida and will be co-featured by a welterweight grudge match between Matt Hughes and Matt Serra.
