Canadian welterweight Rory McDonald has been forced out of a highly anticipated rematch with former interim champion Carlos Condit next month with an undisclosed injury.

McDonald was scheduled to take on Condit in the co-main event of UFC 158 in Montreal on March 16, but has picked up a problem in training and will not fight on the card.

Condit will now face leading contender Johny Hendricks, who has been moved from a bout with Jake Ellenberger and signed a contract to fight the 'Natural Born Killer' earlier today.

Ellenberger is still expected to fight at the Bell Centre, against a new opponent to be named later this week.

UFC 158 is headlined by a welterweight title fight between George St-Pierre and Nick Diaz.
