Mickelson shakes off injury

Phil Mickelson has shaken off a muscle injury and will take part in this week’s Houston Open.

The world number five was a major doubt for the $6.4million event in Humble as well as the Masters next week after he withdrew from last week’s Texas Open with a pulled muscle in his right side.

However, he has recovered and even had two days of “light practice” at Augusta National.

“I played nine holes today at Augusta and I felt pretty good,” the 43-year-old five-time major winner said on his official website.

“I was able to swing fine. It just felt sore as opposed to hurting. I feel that to give myself the best chance at the Masters I have to play in Houston.

“If I thought I would injure myself further I would have withdrawn from the tournament but the last few days have been good.”

Mickelson will be one of 34 major winners teeing off at the Golf Club of Houston on Thursday with the likes of Rory McIlroy and Webb Simpson also in the field.
