Rory MacDonald is being groomed as a rising star in the UFC.

With his association with Tristar Gym in Canada, MacDonald trains with the likes of UFC welterweight champion Georges St-Pierre and his coach, Firas Zahabi.

This Saturday night, MacDonald will be in the biggest – and most important – fight of his young career, taking on Che Mills in the co-main event of UFC 145: Jones vs. Evans from Atlanta.

Since debuting with the UFC in 2010, MacDonald has lost just once, falling by TKO to Carlos Condit in a fight he was leading. He rebounded with a decision victory over Nate Diaz and knocked out Mike Pyle in his next fight.

“I began training with Tristar in August of last year,” said MacDonald, in a recent interview with FightLine. “Training with Firas has been awesome and all the other coaches have been really beneficial. By training here I have specialized coaches for MMA, boxing, strength and conditioning, and wrestling. Another benefit is all the top training partners that come here.”

In Mills, MacDonald will be facing a more veteran fighter, but one with just a single fight inside the Octagon. “I really don’t know all that much about him,” the native of British Columbia, Canada said. “That’s how I like it, the less I know, the better.”

If you haven’t seen MacDonald compete yet, you are in for a treat this Saturday night. He has knockout power – five victories via TKO or KO – and excellent submission – six wins via tapout. Expect to see another level of MMA from the 22-year-old against Mills.
