Brooks Koepka's U.S. Open status uncertain after withdrawing from RBC Canadian Open

One of golf's headliners could be at risk of missing the 2026 U.S. Open. 

Five-time major champion Brooks Koepka withdrew from the final round of the RBC Canadian Open on Sunday because of a lingering left-hand injury. The issue left him struggling to grip his clubs. 

Brooks Koepka discusses injury 

"Yeah, I don't know what it is. I'm struggling to grip the club with my ring finger and pinkie finger, so I can't grip it," Koepka said (h/t Field Level Media). "So the club is kind of just, my fingers would come loose, it's kind of numb. I don't know what the deal was, but hopefully we'll figure it out." 

Whatever the injury is, it's awful timing for Koepka. The U.S. Open begins Thursday at Shinnecock Hills Golf Club in Southampton, New York. And even if he does play in the four-round tournament, the injury may prevent him from regaining his rhythm. 

Brooks Koepka looked poised to make noise at U.S. Open, but it's uncertain if he will after injury

Koepka, who hasn't won a tournament since the 2023 PGA Championship, appeared to be regaining his groove heading into the tournament. He tied for 14th at the CJ Cup Byron Nelson and looked strong at the Canadian Open. He shot a 64 (6-under-par) and 68 in the first two rounds of the tournament before scoring a 72 in the third round. 

Koepka isn't considered a favorite to win the U.S. Open, but he's expected to be a factor. As of Sunday, FanDuel Sportsbook gives him +2700 odds to win the tournament. Scottie Scheffler, the No. 1 golfer in the world, has the best odds (+550) to win the U.S. Open. These odds don't account for Koepka's injury.

Figure on Koepka's chances plummeting if he plays in the U.S. Open. How can he win when he can barely grip a club?
