BOISE, Idaho (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.
``Injuries are part of the sport and you try to avoid them as an athlete as much as you can,'' Djokovic said. ``The nature of the injury is still to be determined.
``One hour, one hour and a half after the end of the match, all I can say is it doesn't look good.''
Djokovic had the ankle tightly wrapped and had taken anti-inflammatory pills. He plans to travel home to Monte Carlo to have an MRI.
He was hoping to be ready to play the Monte-Carlo Rolex Masters, which he considers his home event, but didn't sound convinced he'd be ready to play when it gets underway April 14.
``It's swollen, and when it's swollen it's definitely not a good first sign,'' Djokovic said. ``I'm going to do everything I can in my power to recover till that tournament. How realistic that is, I don't know what to tell you.''
Djokovic indicated that the consequences of playing on the ankle didn't enter his decision in continuing with the match.
``I was just thinking of just winning this match and bringing the tie win to Serbia and I'm glad I did,'' he said. ``On the other-hand, I'm a bit concerned it's not comfortable feeling what I feel with the ankle.
``If it was a normal ATP Tour event I don't know, but probably my mindset would've been different. I had a lot of motivation and it just felt logical that you do your best to finish the match.
``Luckily it was a win.''
