UFC welterweight Rory MacDonald is quickly on the rise in the Welterweight division. Many wonder if the time will come that he and his training partner, fellow Tri-Star Gym member Georges St. Pierre, will be on a collision course for the Welterweight title.

In a recent interview with The Score, MacDonald talked about his meteoric rise in popularity, particularly his recent co-main event win over Che Mills and how many new casual fans that garnered him.

MacDonald also spoke of his next opponent, BJ Penn, and how the UFC urged him to call Penn out, knowing Penn would accept the challenge to face Tri-Star Gym's "young stud." What challenges does Penn pose for MacDonald?
