Four-time major winner Brooks Koepka has pulled out of next week's US Open because of injury.
The 30-year-old American began 2020 as world number one but has slipped to eighth in the rankings having had hip and knee problems all season.
Koepka has not played since he missed the cut at the Wyndham Championship in August.
"I'm looking forward to getting healthy and competing at 100% again very soon," he wrote on Twitter.
This year's US Open takes place at Winged Foot Golf Club in New York.
Koepka won the tournament in 2017 and 2018, and the US PGA Championship in 2018 and 2019.
