Will Zalatoris withdrew during the third round of BMW Championship on Saturday due to a back injury.
Zalatoris shot a 3-under-par 139 over the first two rounds to enter play on Saturday five shots behind leader Adam Scott of Australia.
He was four shots back when he appeared to sustain his injury after teeing off on the fourth hole Saturday. He gingerly walked down the fairway and finished the hole, however attempts to stretch himself out prior to the fifth hole did not go well and he opted to withdraw from the tournament.
