MONTREAL – Rising Canadian UFC welterweight star Rory MacDonald had a setback in his recovery from a neck injury after tweaking it during a workout Tuesday.

Following the setback there is no timetable for his return to the Octagon.

“(Rehab) was going good, but then yesterday I kind of hurt it again, so after today I’m going to get someone to check it out,” MacDonald told Sportsnet.ca Wednesday at the UFC 158 open workouts.

“I was trying to get back slowly into training and I was just doing technique and I just tweaked it.”

MacDonald was scheduled to fight Carlos Condit at Saturday’s UFC 158 but was forced to withdraw after injuring his neck while training in mid-February.

The 23-year-old native of British Columbia, who currently lives and trains in Montreal, was signing autographs for fans during the open workouts Wednesday while his peers warmed up in a cage in the middle of the Complexe Desjardins Grande-Place shopping mall in downtown Montreal.

MacDonald explained that it’s a very frustrating situation to be in.

“It’s a bit annoying. It’s a bit disappointing seeing all the guys do their thing,” MacDonald said. “Fight week is exciting so the best word is disappointing. I feel sad.”

MacDonald expressed that he is still interested in fighting Condit, who meets Johny Hendricks this weekend, when he is healthy enough to fight, but added “we’ll see how (UFC 158) works out.”
