When practicing for Thursday’s opening round of The Players Championship, a college golfer heckled the four-time major winner from behind the 18th tee box at the Ponte Vedra Beach, Fla., course, with McIlroy later taking matters into his own hands — literally.

University of Texas golfer Luke Potter has apologized after he reportedly was removed from the grounds at TPC Sawgrass earlier this week for heckling star golfer Rory McIlroy. Video of the incident spread on social media earlier this week.
