Injury bug takes bite out of Phil

With the Masters looming in less than two weeks, Phil Mickelson pulled out of Saturday's third round of the US PGA Tour's Texas Open with a pulled muscle.

Mickelson was one-over for the day after three bogeys and two birdies when he withdrew at the par-five second hole, his 11th of the round.

He said he felt the injury when teeing off at the first, his 10th hole of the day.
