Back injury sidelines Canadian golfer Graham DeLaet from PGA Tour until 2012

MISSISSAUGA, Ont. - Graham DeLaet will sit out the rest of the PGA Tour season while recovering from a back injury.

The 29-year-old from Weyburn, Sask., plans to return to competition at the Sony Open in January. He only played a handful of tournaments in 2011 after undergoing surgery on a herniated disc in January.

"He is almost 100 per cent, but not quite there," DeLaet's agent George Sourlis said Wednesday. "The aim is for Graham to be 100 per cent when he resumes his full time schedule on the PGA Tour, and that will require a little more time."

DeLaet will use a major medical exemption in 2012, which will give him 26 tournaments to earn the equivalent of 125th place on this year's money list and keep his playing privileges.

He first attempted a comeback in June, but had soreness and stiffness return after entering three tournaments. DeLaet then missed the cut at last week's Albertsons Boise Open on the Nationwide Tour.

"I am disappointed that the rehabilitation process has taken longer than anticipated but I feel great," said DeLaet. "I'm playing some of the best golf of my career but still experiencing some lingering discomfort at the end of my rounds. With just a couple more months of rehab I'll be in great shape to resume my playing career."
