Weir started feeling pain in his right elbow before the British Open last month.
TORONTO (AP) -- Mike Weir has a partially torn ligament in his right elbow and is likely out for the rest of the season.
Weir told The Canadian Press on Tuesday that he had an MRI exam over the weekend. He plans to rest the elbow and seek treatment to avoid surgery.
The Canadian left-hander had elbow pain before the British Open in July but thought it was tendinitis. A conversation with PGA pro Scott McCarron at last week's Wyndham Championship prompted Weir to seek medical attention.
McCarron told Weir that he had a similar injury but continued to play while getting treatment. That resulted in a complete tear, which required surgery and a year off the tour.
Weir is coming off a season of eight missed cuts. His best finish was sixth at the Bob Hope Classic.
