Video: Georges St. Pierre, Rory MacDonald Q&A live stream from UFC 186 weigh ins

Well now ... this is interesting.

Former Ultimate Fighting Championship (UFC) welterweight champion Georges St. Pierre -- who is rumored to be making his return for one more UFC fight -- will join his Tristar team mate and heir to the 170-pound throne, Rory MacDonald, for the UFC 186 fan Q&A this afternoon prior to the "Johnson vs. Horiguchi" weigh in event (results and video here) in Montreal, Quebec, Canada.

The live stream kicks off at 2:30 p.m. ET in the embedded video player above.

"Ares" was originally scheduled to compete at UFC 186, but was promoted to a UFC 189 title fight rematch opposite Robbie Lawler when Hector Lombard flunked his drug test. "Red King" has already made it clear he won't fight "Rush," so a win this July rules GSP out of the title picture.

Or so they say.
