Jason Day withdrew from the CJ Cup with a neck injury after playing one hole of the final round, the PGA Tour announced.

Day was in the penultimate group on Sunday after entering the day trailing Russell Henley by five shots at 10-under par. The Aussie made a triple-bogey on his first and only hole before pulling out halfway through No. 2.

He was leading the field in strokes gained: tee to green through three rounds at Shadow Creek Golf Course.
