Henrik Stenson has emerged as an injury concern for next month's Ryder Cup after he was forced to withdraw from The Barclays following his first round.
Stenson fired an erratic three-over 74 at Bethpage Black, mixing five birdies with three bogeys, one double and one triple, and he then revealed he had suffered a recurrence of a right knee injury.
The Swede had surgery on the same knee at the end of last year, but the problem resurfaced during the second day of the US Open at Oakmont in June and he pulled out without completing his round.
He bounced back to make his major breakthrough with a record-breaking performance in The Open at Royal Troon, and also collected an Olympic silver medal in Rio earlier this month.
But the world No 4 will now have a scan on his knee following his withdrawal from the first of the four FedExCup Play-Off events in New York, and European Ryder Cup captain Darren Clarke will be anxiously awaiting the results.
Stenson issued a statement which read: "My right knee, which required surgery in December, 2015, has flared up again.
"Regrettably, I need to withdraw this week to allow time for an MRI and see what the next step is."
