Brooks Koepka withdrew from the final round of the RBC Canadian Open on Sunday morning, unable to grip a golf club after a mysterious hand injury flared up during Saturday's third round at TPC Toronto. The five-time major champion now faces an uncertain path to next week's U.S. Open at Shinnecock Hill, the same course where he won his second U.S. Open title in 2018.
The PGA Tour announced the withdrawal shortly before Koepka's final-round tee time, citing a hand injury. Koepka sat at six under par and seven shots off the lead when he pulled out, forfeiting any chance to collect FedEx Cup points in what had been a solid week in Caledon, Ontario.
For a 36-year-old who left LIV Golf and fought his way back to the PGA Tour at the start of 2026, the timing could hardly be worse. The U.S. Open begins Thursday. Shinnecock Hill holds personal history for Koepka. And the injury, by his own account, is something he has never dealt with before.
After grinding through a third-round 72 on Saturday, Koepka spoke with reporters and described the problem in blunt terms. As Fox News reported, Koepka said he could not maintain his hold on the club:
"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."
He went further, describing a loss of feeling that made it impossible to play at a competitive level:
"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."
That last line, "hopefully we'll figure it out", tells you everything about where things stand. Koepka does not have a diagnosis. He does not know what caused the numbness. And he said the issue had never surfaced before it appeared in Canada.
Koepka's return to the PGA Tour under the Returning Member Program has been a legitimate feel-good story in professional golf this year. In 11 starts before the Canadian Open, he posted six top-20 finishes, including a T12 at the Masters in April. He competed at the PGA Championship at Aronimink Golf Club in Newtown Square, Pennsylvania, in May.
None of that matters if his hand does not cooperate.
The withdrawal raises a straightforward question that no one, apparently not even Koepka, can answer right now: Will he tee it up at Shinnecock Hill on Thursday? The U.S. Open is the crown jewel of American golf, and Koepka has a deeper connection to Shinnecock than almost anyone in the field. He won there in 2018, part of a back-to-back U.S. Open run that cemented his reputation as one of the most formidable major championship performers of his generation.
Walking away from a return to that course because of a finger injury he cannot even identify would be a bitter pill.
What makes this situation difficult to read is the absence of information. Koepka did not describe a specific incident, no awkward swing, no collision, no obvious moment when something went wrong. He described numbness and loss of grip strength in his ring finger and pinkie finger, two digits essential to controlling a golf club under pressure.
Whether Koepka has sought or received medical evaluation since withdrawing is not publicly known. The PGA Tour's announcement confirmed only the withdrawal and the general category of "hand injury." That leaves fans, oddsmakers, and Koepka himself in the same place: waiting.
For a player who has battled knee injuries and other physical setbacks throughout his career, the uncertainty is familiar territory. But the stakes are unusually high with a major championship days away.
Shinnecock Hill is not just another stop on the schedule. It is one of the most storied venues in American golf, and for Koepka, it carries personal significance as the site of his second major victory. A healthy Koepka returning to Shinnecock after his LIV Golf departure and PGA Tour comeback would have been one of the best storylines of the week.
Now the storyline is whether he can show up at all.
Koepka's 2026 season has shown he still has the game to compete at the highest level. Six top-20 finishes in 11 starts is not the résumé of a player coasting on reputation. He earned his way into contention at multiple events. He belongs in a U.S. Open field.
But golf is a grip-and-rip sport at the professional level. If a player cannot feel his fingers wrapping around the club, no amount of talent or competitive fire can compensate. Koepka knows that better than anyone, which is likely why he made the call to withdraw Sunday morning rather than push through another 18 holes of compromised golf.
The next few days will determine whether Koepka's Canadian Open withdrawal is a minor footnote or a major blow to his comeback season. If the numbness resolves and he arrives at Shinnecock Hill ready to compete, Sunday's withdrawal will be remembered as a smart, cautious decision to protect his body for the tournament that matters most.
If it does not resolve, Koepka will miss a U.S. Open at the course where he once hoisted the trophy, and the questions about his long-term health will grow louder.
The man said it plainly on Saturday: "I don't know what the deal was." Until he does, everything else is guesswork.
Five major titles buy you a lot of goodwill. They do not buy you a clean bill of health on a four-day deadline.
