Jason Day has withdrawn from the PGA Tour season-ending and playoff-ending Tour Championship with a back injury, meaning the world No. 1 will not be able to win the FedEx Cup.
Day withdrew after seven holes of the second round at East Lake Golf Club in Atlanta. In bizarre fashion, Day used driver off the deck from the rough on his final hole. Hitting driver off the turf is a demanding shot requiring a lot of torque under normal circumstances. It's even more strenuous out of the rough. However, Day did it anyhow, followed by pulling out.
Day also withdrew from his last tournament, the BMW Championship two weeks ago, after nine holes of the final round.
Heading into the Tour Championship ranked fourth in the points standings, Day said he was "cautiously optimistic" about his chances of getting through the final tournament of the PGA Tour season.
