Luke Donald will not be available for next month's Ryder Cup after undergoing surgery on a wrist injury.

The Englishman was an outsider for a wildcard for Nick Faldo's team to face the United States in Kentucky after a season hampered by a tendon injury.

The 30-year-old's appearances have been restricted this year and he was forced to miss the recent Open and USPGA tournaments.

"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.
