Rory McIlroy took matters into his own hands at The Players Championship earlier this week after being heckled by a fan.

Fields indicated that Potter has written letters of apology to several people: McIlroy; PGA Tour commissioner Jay Monahan; Brendan von Doehren, the director of PGA Tour University; and Scott Schroeder, men's golf coach at the University of North Florida. Fields would not disclose to Golf.com whether Potter was facing any disciplinary action.

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.
