FILE - In this Feb. 2, 2017, file photo, Tiger Woods reacts on the 11th hole during the first round of the Dubai Desert Classic golf tournament in Dubai, United Arab Emirates. Woods pulled out of his next two tournaments because of ongoing back problems, a somber outlook for a 14-time major champion whose comeback barely lasted three tournaments before another setback. Woods said Friday, Feb. 10, 2017, on his website that he was still coping with back spasms that he attributed to his withdrawal from the Dubai Desert Classic last week.
