Another blockbuster bout has been scheduled for UFC 156 according to sources close to the event, this one between top middleweight contenders Michael Bisping and Vitor Belfort.

The event is set for Jan. 19 in an, as of yet, undetermined Brazilian city. Cities currently being considered to play host, however, so far include; São Paulo, Porto Alegre and Florianópolis, and Rio de Janeiro.

The card already features a much-anticipated featherweight clash between UFC featherweight champion Jose Aldo and former UFC lightweight champion Frankie Edgar.

Bisping (23-4) comes into the bout with an impressive 5-1 record in his last six fights. During the streak, he's has collected victories over Dan Miller, Yoshihiro Akiyama, Jorge Rivera, Jason Miller and Brian Stann.

His lone defeat came at UFC on FOX 2 where he dropped a controversial split decision loss to top middleweight contender Chael Sonnen.

His opponent, Belfort (21-10), a former UFC light-heavyweight champion, comes into the bout with a 7-2 record over his last 9 bouts. Over that stretch he's hammered out victories over Ivan Serati, James Zikic, Terry Martin, Matt Lindland, Rich Franklin, Yoshihiro Akiyama and Anthony Johnson. He's also finished six out of his last seven opponents.

His two defeats over that period have come at the hands of UFC middleweight champion Anderson Silva, and UFC light-heavyweight champion Jon Jones.

In his last bout, Belfort became the first fighter to ever truly put the seemingly unbeatable Jones in serious trouble, as he had the champ in a tight armbar in the first round which strained a ligament in his elbow, however, the resilient Jones would escape, and eventually submit an exhausted Belfort in fourth round with an americana.
