Hubert Hurkacz, the No. 7 seed, was forced to retire from his second-round match at Wimbledon because of a knee injury suffered during the match on Thursday in London.

With Arthur Fils of France leading 7-6 (2), 6-4, 2-6, 6-6, the players were deep into the fourth-set tiebreaker when Hurkacz dove to make a shot and landed on his right knee. With an 8-7 set point in his favor, Hurkacz called for a medical timeout, returned to the court to play two points, then retired with Fils at set point in the tiebreaker.

The 20-year-old Fils will be playing in the third round of a Grand Slam event for the first time.

“It’s very tough to win a match like this against a friend,” Fils said in his on-court interview. “We were playing super good in the fourth set. We had some great points, and he was jumping everywhere. I’m really sorry for him and I hope he will recover very quickly.”

Hurkacz, of Poland, is the third top 10-seed out of the men’s tournament.

No. 6 Andrey Rublev of Russia and No. 8 Casper Ruud of Norway fell in the first and second rounds, respectively.

The severity of the injury to Hurkacz was not immediately known. He is scheduled to represent Poland in the Paris Olympics later this month.
