U.S. Open tournament director David Brewer says Eugenie Bouchard has pulled out of women’s doubles and mixed doubles after getting a head injury when she slipped and fell in the locker room.
Brewer issued a statement Saturday, a day after Bouchard won her third-round singles match. Bouchard, the runner-up at Wimbledon last year, is seeded 25th in singles.
Brewer says it hasn’t been determined whether Bouchard will stay in the singles event.
The Canadian was entered in doubles with Elena Vesnina and in mixed doubles with Nick Kyrgios.

Roger Federer finally got broken — twice, actually — but was in control pretty much the entire way en route to the fourth round of the U.S. Open for the 15th consecutive year.
The No. 2-seeded Federer beat No. 29 Philipp Kohlschreiber of Germany 6-3, 6-4, 6-4 on Saturday.
Federer has won each of his nine sets through three matches, dropping only a total of 20 games so far.
The 17-time major champion, who won the U.S. Open five times in a row from 2004-08, entered the match against Kohlschreiber having won 72 straight service games, including all 23 in New York.
Kohlschreiber broke Federer once in each of the last two sets — and Federer broke right back each time.
Federer, now 10-0 against Kohlschreiber, faces 13th-seeded John Isner of the United States for a spot in the quarterfinals.

British qualifier Johanna Konta ran her winning streak to 16 matches by beating 18th-seeded Andrea Petkovic of Germany 7-6 (2) 6-3 to reach the fourth round of a Grand Slam tournament for the first time.
It was an impressive follow-up for Konta, whose previous match was a 7-6 (4), 6-7 (4) 6-2 victory over Wimbledon runner-up Garbine Muguruza that lasted 3 hours, 23 minutes, the longest U.S. Open women’s match since the introduction of the tiebreaker in 1970.
Konta’s winning streak includes three main-draw U.S. Open matches, three qualifying matches at Flushing Meadows, and nine matches at low-tier events.
Petkovic appeared bothered by the heat during the second set. Trailing 3-0, she had the trainer on court taking her blood pressure and pulse.
The 97th-ranked Konta needed six match points to finish the victory in 1 hour, 56 minutes.
Konta failed to take advantage of three match points in the 18-point seventh game, allowing Petkovic to break her serve.
Two games later, Konta secured the win on her third match point of the ninth game, when Petkovic sailed a forehand long.

No. 5 seed Petra Kvitova has moved into the fourth round of the U.S. Open with a 6-2, 6-1 win against 32nd-seeded Anna Karolina Schmiedlova of Slovakia.
It will be two-time Wimbledon champion Kvitova’s third appearance in the fourth round at Flushing Meadows, but she is 0-2 at that stage.
Kvitova never presented Schmiedlova with a break opportunity in the 66-minute match. The Czech star converted five of her nine break chances.
