Jason Day withdrew from the BMW Championship on Sunday after eight holes in his final round at Crooked Stick Golf Club in Carmel, Ind.
Citing back issues, Day entered the round a lengthy 13 strokes back of leader Dustin Johnson. His round got off to a rough start, too, with a bogey and double bogey over his first three holes.
The World No. 1 player has been dealing with back issues this season -- tweaking it during the WGC-Dell Match Play in Austin, which he would go onto win.
The withdrawal won't jeopardize his chances at the Tour Championship -- Day is still currently projected fourth in the FedEx Cup points standings.
With the tournament two weeks away, he should have plenty of time to heal before competing in the final FedEx Cup playoff event at East Lake Golf Club in Atlanta.
