For those of you wanting to see Rory MacDonald make a quick return to the Octagon, prepare for disappointment.

"Ares" stopped by today's UFC 158 open workouts and revealed to Sportsnet.ca that the injury that initially knocked him out of his rematch against Carlos Condit was aggravated yesterday.

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

Obviously, it had to be frustrating watching his comrades (except Nick Diaz) strut their stuff at the open workouts for an event he was supposed to co-headline, and the Tristar standout made his feelings known.

"It's a bit annoying. It's a bit disappointing seeing all the guys do their thing. Fight week is exciting so the best word is disappointing. I feel sad."

MacDonald is currently ranked number four on the official list of top UFC welterweight contenders and is coming off a tremendous performance against B.J. Penn in a one-sided thrashing this past December.

Long hailed as one of the best prospects in the welterweight division, the talented Canadian was hoping to prove himself by avenging his lone career loss to Condit.

Neck injuries can be tricky, especially now that MacDonald is going to get it checked out. MMAmania.com will keep you posted if any new developments occur and when we can expect to see "Ares" inside the cage again.
