Querrey reached the Wimbledon quarterfinals last year. Tsonga, a two-time Wimbledon semifinalist, also reached the quarterfinals at the All England Club last year.

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."

Roger Federer and Novak Djokovic are among the players whose Wimbledon third-round matches are scheduled to be completed before the tournament heads to its traditional break on the middle Sunday.

For the first time in 33 years, a pair of brothers will both be competing in the third round at the All England Club. Back in 1984, it was Tim and Tom Gullickson. This time, it's 10th-seeded Alexander Zverev and his older sibling, 27th-seeded Mischa.

Mischa plays seven-time champion Federer on Centre Court on Saturday. Alexander faces Sebastian Ofner, a 21-year-old Austrian qualifier who is ranked only 217th.

The past two Wimbledon women's runners-up, No. 1-ranked Angelique Kerber and Garbine Muguruza, also will be trying to reach the second week.
