(AP) Novak Djokovic wasn't optimistic about his right ankle injury after lifting Serbia to an insurmountable 3-1 lead over the U.S. with a 7-5, 6-7 (4), 6-1, 6-0 win over Sam Querrey in a Davis Cup quarterfinal.
The world No. 1 twisted the ankle while hitting a forehand at 1-1, 30-40 on Querrey's serve in the third game of the match at the Taco Bell Arena on Sunday.
He continued playing and about an hour after the match he said the injury "doesn't look good."
He says the ankle is "swollen and when it's swollen it's definitely not a good first sign." He questioned whether he'd be ready to play in the Monte-Carlo Masters, which he considers his home event, when it starts April 14.
Djokovic plans to travel home to Monte Carlo to have an MRI.
