Tiger Woods has admitted that he would not be able to provide any help to the United States Ryder Cup team due to his back problem.
The 14-time Major champion ruled himself out of Tom Watson's team ahead of the tournament at Gleneagles.
"Physically I just couldn't do it, I wouldn't be ready," Woods told Sky Sports News. "I just couldn't help the team. It was time to shut down, get stronger, get more explosive again and get back for next year."
Woods, who has competed for the US seven times, needed a captain's pick to take part this year after missing the cut at the US PGA Championship almost a fortnight ago.
The tournament between the US and Europe will get underway on September 23 in Scotland.
