A welterweight matchup between BJ Penn and Nick Diaz, previously scheduled for the co-main event, will now headline the Oct. 29 card in Las Vegas, but will remain a three-round fight.
According to White, St-Pierre is currently expected to be out only a “couple of months” and Condit will wait for his title shot, but GSP will apparently see a doctor soon that should confirm the timeline for his return barring any setbacks.
The moves put Diaz back into the UFC 137 main event just over a month after the UFC swapped him and Condit when he failed to appear for a pair of press conferences. White initially suggested that Diaz could be cut, but quickly booked him to fight Penn instead and recently said he could still earn a shot at the title with a win.
Diaz (25-7) scored a first-round TKO of UFC veteran Paul Daley in April to defend his Strikeforce title and earn another shot in the UFC with his 10th-straight win, while Penn (16-7-2) returned to 170-pounds following a pair of losses to Frankie Edgar with a 21-second KO of Matt Hughes in November before fighting Jon Fitch to a draw in February.
