ATLANTA -- Jason Days PGA Tour season officially ended two days earlier than expected, when he withdrew from the Tour Championship due to a lingering back injury midway through the second round on Friday afternoon.The injury is a strained ligament in his lower right back with a muscle spasm. He withdrew as a precautionary measure, read a statement from Days management team.It is the same back injury that forced Day, the worlds No. 1-ranked player, to withdraw from the BMW Championship two weeks ago.I put the tee in the ground at the BMW Championship, and my back went out, Day explained earlier this week. Last time it went out, I changed a diaper. So its nothing where I go and physically make a move at it during a swing and my back goes out. It literally is from the smallest things -- picking up a pillow, picking up something off the ground, or just moving the wrong way.Day was playing the eighth hole at East Lake Golf Club when he withdrew on Friday. After hitting his drive into the water, he took a drop, then hit driver off the deck before calling for medical attention and leaving the course.As the fourth-ranked player in the FedEx Cup, Day could have earned the season-long title and $10 million first-place prize with a victory this week. He will remain the games top-ranked player, no matter what, despite second-ranked Dustin Johnson?being in contention heading into the weekend rounds.If theres a silver lining to Days timing, its that he wasnt expected to tee it up competitively again for at least two months. The next two events on his schedule are believed to be the Australian Open (Nov. 17-20), followed by the World Cup of Golf (Nov. 24-27), both in his native Australia.His 2016-17 season officially concludes with victories at the Arnold Palmer Invitational, WGC-Dell Match Play and The Players Championship. He finished in the top-10 in 10 of his 20 PGA Tour starts. Wholesale Shoes Nike . It was hard for Luck to pull off another comeback, or even get into the end zone, while standing on the sideline.
