Sept 16 (Reuters) - Four-times major winner Brooks Koepka confirmed his participation in next week"s Ryder Cup, after his commitment to the competition was called into question. In an interview with Golf Digest this week, Koepka described the biennial team event between the United States and Europe as "a bit odd" and mentally challenging, saying that he might not be cut out for team sports.

"I"ll be there. I"m good to go," he told Golfweek. "I"m feeling good. Been doing my rehab, doing everything I need to do to be ready for the Cup. I"ll be there ready to play."

"I couldn"t continue because I had no grip strength in my left hand," he added. "When I hit the root I thought it was a stinger and my wrist was feeling weird. I lost feeling to my elbow for a bit. "The MRI showed us some stuff and just making sure it"s calmed down and got everything worked out. Grip pressure has gotten back to normal. Some ice, some rest, some soft tissue work and some rehab and we"re good to go" The Ryder Cup, postponed last year because of the COVID-19 pandemic, will be played from Sept. 24-26 at Whistling Straits in Wisconsin.
