Golf: American Brooks Koepka's US Open status in doubt after knee surgery

Brooks Koepka is looking less likely to return to golf for next month's Masters.

The world No.12 has told Golfweek that he underwent surgery on his right knee last week in California.

The four-time Major winner noted that he sustained "right knee cap dislocation and ligament damage". 

When asked about his potential participation in the Masters, Koepka says: "Whatever my body says, I'm going to listen."

Koepka posted a collage of photos to Twitter, including an image of his bandaged right knee and another of him on crutches.

The 30-year-old has been sidelined since tying for second place at the WGC-Workday Championship earlier this month.

He withdrew from The Players Championship with a strained right knee.

The Masters is scheduled for April 8-11. 

Koepka has finished tied for second (2019) and tied for seventh (2020) in his last two Augusta National showings.

Koepka won the 2017 and 2018 US Opens, as well as the 2018 and 2019 PGA Championships.
