Brooks Koepka (hand) WDs from RBC Canadian Open

Brooks Koepka acknowledged an injury to his hand after he labored through a 2-over-par 72 on the third round at the RBC Canadian Open on Saturday.

On Sunday morning, Koepka officially withdrew from the tournament at Caledon, Ontario.

The five-time major champion admitted that he was struggling with the grip of his club ahead of the fourth round.

"Yeah, I don't know what it is. I'm struggling to grip the club with my ring finger and pinkie finger, so can't grip it," Koepka said.

"So the club is kind of just, my fingers would come loose, it was kind of numb. I don't know what the deal was but hopefully we'll figure it out."

He opened the tournament with rounds of 64 and 68.

Koepka, 36, was spotted receiving treatment on the 11th tee box at the TPC Toronto at Osprey Valley (North Course) during the third round.

"Yeah, the whole warm-up, I felt fine, I was absolutely good," he said. "Then got to the range and went to grip the club and I just couldn't even grip it.

"So it lasted -- it was all day. Felt better the last few holes. I don't know if that's just the meds kicked in or what it is. But hopefully we'll figure it out now."

Figuring it out is paramount given the U.S. Open is next week at Shinnecock Hills in Southampton, N.Y. He won the second of his two consecutive U.S. Open championships at Shinnecock Hills in 2018.

Koepka has been back on the PGA Tour since January after more than three years away with LIV Golf. He's placed in the top 20 in six events this year but his next win would be his first in a standard PGA Tour event since the 2021 WM Phoenix Open.
