Tiger Woods has suffered another setback after being forced to withdraw from the Farmers Insurance Open at Torrey Pines with injury.
After just 11 holes, Woods had to pull out citing back problems as the cause yet again. He was two over par.
The early departure comes off the heels of shooting a career-worst 82 in the second round at Phoenix last week and dropping out of the top 50 for just the second time in his career.
Things have not been going well for the 14 time major champion, playing in just his second tournament of the season after returning from surgery which caused him to miss least year's Master's and US Open.
Wood's back injury was evident as his playing partners Rickie Fowler and Billy Horschel both helped him pick his ball out of holes.
Speaking to reporters, Woods revealed: "My glutes keep shutting off and that causes me pain in my back. It got worse as we stood waiting on the putting green during the delay and I tried warming up my glutes, but it just wasn't working for me.
"When we went back out, it just got progressively worse."
