UFC welterweight prospect Rory MacDonald recently participated in the UFC 154 fan Q&A session before the UFC 154 weight-ins.

During the Q&A, MacDonald discuss a variety of issues, chief among them an explanation for his decision to never fight his TriStar teammate and current UFC welterweight champion George St. Pierre.

MacDonald is considered one of the top welterweights on the UFC's roster, and appears to be just a few wins away from a potential title shot, but he made it crystal clear that he has no interest in ever facing St. Pierre.

"It's a question I hear a lot," MacDonald said. "Me and Georges are not gonna fight. Me and him are friends and we are very close training partners, and it's just not gonna happen. I don't wanna sacrifice a friendship and my spot at TriStar. I really feel being there has made me develop leaps and bounds as a fighter, so I wouldn't disrespect Georges or the gym in that way.

"I know he has seniority as a title holder, so I really feel were just gonna see what happens. I'm taking one step at a time. I'm fighting B.J. [Penn], and I plan on beating him. I plan on getting my rematch with Carlos in 2013."

With St. Pierre showing no signs of slowing down, or losing the welterweight title that he's defended seven times throughout his UFC career, one wonders if MacDonald would ever consider moving up to middleweight.

"Maybe, we will see how it goes," MacDonald said. "I have no doubt that I will fight at middleweight at some point in my career. Not because I'm too big for 170 lbs, it's pretty easy for me to make 170 lbs. I wanna fight at middleweight as well. Will see how it goes and how fast I move up."
