Tiger Woods returns, take 10

Tiger Woods is playing the Hero World Challenge this week, making it the 10th time he has returned from layoffs of 10 weeks or longer.

The most recent layoff was caused by fusion surgery on his lower back, his fourth back surgery since March 2014.

Woods only started taking full swings two months ago, though he has reported no pain in his back. The Hero World Challenge has an 18-man field with no cut.
