No. 1 women's doubles player Bethanie Mattek-Sands of the U.S. says she needs surgery on her right knee after dislocating her kneecap and rupturing her patella tendon during a singles match at Wimbledon.
Mattek-Sands says on Facebook Live that "it's been an emotional and painful roller-coaster the past few days."
She was wearing a black brace on her right leg.
Tearing up, Mattek-Sands calls it "one of the most painful injuries that I've had - and I've had a few in my career." The 32-year-old American was hurt early in the third set of a second-round match on Thursday.
She says she will fly to New York on Sunday to see more doctors and will be sidelined "for a while."
