In another unfortunate turn of events regarding Georges St. Pierre, the longtime UFC welterweight champion has suffered a torn ACL and will be sidelined for nearly a year.
UFC President Dana White announced the news early Tuesday. Due to St. Pierre's anticipated lengthy layoff, top contender and one-time Strikeforce welterweight title holder Nick Diaz will face former WEC champion Carlos Condit for the interim UFC welterweight belt at UFC 143 on February 4 in Las Vegas, Nevada.
St. Pierre was slated to face Diaz in a highly-awaited matchup at the event. A previously scheduled bout between St. Pierre and Diaz for this past October was scrapped after Diaz failed to show up to multiple pre-fight media requirements.
Condit was then penciled in to face St. Pierre, but the Canadian went down with a knee injury. The UFC opted to have Condit wait on the sidelines while Diaz remained on the card against former two-division champion B.J. Penn.
Diaz handed Penn the worst loss of his career, forcing White to once again hand Diaz a title show against St. Pierre on Super Bowl weekend. Condit was to face "TUF" product Josh Koscheck, who is now in limbo in regards to his participation at UFC 143.
It will be the first ever meeting between Diaz and Condit, who successfully defended the WEC welterweight title three times before moving to the UFC in 2009, where he has now won four straight fights. Diaz picked up his first UFC win since 2006 in defeating Penn this fall. The 28-year-old is currently riding a 10-fight win streak.
