Tiger Woods' long awaited comeback may be delayed again due to an Achilles heel injury he suffered Sunday while playing at the Cadillac Championship.

Woods was showing signs of wear since the 4th hole, but after he completed 11 holes his limp became so pronounced that he had to walk limp away. He officially withdrew before the 12th hole.

I felt tightness in my left Achilles warming up this morning, and it continued to get progressively worse, Woods said in a statement. After hitting my tee shot at 12, I decided it was necessary to withdraw. In the past, I may have tried to continue to play, but this time I decided to do what I thought was necessary.

The severity of the injury is not known as of yet.

Woods suffered a similar injury last year at the Augusta National which caused him to miss 2 majors in 2011.

Woods' career has been plagued with injuries because of problems with his left leg. In 2008 had surgery on his left knee to repair cartilage damage that caused him to miss out on three majors that year including the Quail Hollow, the Players Championship, and the Memorial. In June of the same year he had reconstructive surgery again on his left knee and had to sit out the rest of the season.

In 2010 he quit the Players Championship because of a neck strain. In May 2011 Woods missed the U.S. Open for the first time since 1994 due to problems with his Achilles.

It's a shame because he looked like he was coming out this year, swinging it really well, playing good, getting himself into contention, said Rory McIlroy, who also played on Sunday. It's probably just precautionary, but I really hope he's healthy for the Masters, because obviously it would be a great week with him there. He can spark an interest in golf that no one else can.
