Donald ruled out of Ryder Cup

England's Luke Donald has been ruled out of Ryder Cup contention and will miss the remainder of the season after undergoing left wrist surgery.

The procedure was performed by Dr Andrew Weiland at the Hospital for Special Surgery in New York on Monday.

Donald, 30, first suffered the tendon injury during the final round of the US Open in June.

At the time, he opted to try and recover without surgery, but after seeing little progress decided to undergo a procedure.

"While there is never a good time for an injury, the timing of this injury was especially disappointing for me considering it forced me to miss The Open Championship and it comes in a Ryder Cup year," Donald said.

"But taking proper care of it is my highest priority and I'm encouraged by Dr Weiland's experience with this type of injury and his outlook towards my recovery and rehabilitation."

Donald will begin strengthening exercises on the wrist in six weeks, and should be able to begin chipping and putting after three months of recovery and rehabilitation.
