Patrick Reed has revealed he is in hospital recovering from pneumonia.
The 31-year-old has not played since the WGC-FedEx St Jude Invitational after withdrawing from The Northern Trust with an ankle injury.
He said in a statement on the PGA Tour website: "The good news is, my ankle is okay. The bad news is I've been in the hospital with bilateral pneumonia.
"I'm on the road to recovery. Once I'm cleared from the doctors I look forward to returning. I wish you all the best and I can't wait to get back out there!
"Thank you so much for your support, it means a lot to me. Also, a special thank you to the doctors, nurses and staff at The Methodist Hospital in the Texas Medical Center."
