Tiger Woods has ruled himself out of contention for next month’s Ryder Cup because of injury.
The 38-year-old American, who failed to qualify automatically for the Gleneagles event, has been suffering from a persistent back problem.
Woods had surgery in March and has been told not to play by doctors.
Last week’s US PGA Championship was the final tournament to count towards qualification for the US Ryder Cup side, and Woods’ failure left him 70th in the US Ryder Cup standings, 61 places off a qualifying berth.
