Novak Djokovic's head wasn't the problem in his fourth round match today at the US Open.
The ailing Serb, who's already been bugged by injury, went the distance with Spain's Tommy Robredo but prevailed 4-6, 6-2, 6-3, 5-7, 6-3. But along the way Nole hurt his hip, rolled his right ankle, and had more stomach issues. But pure exhaustion was the biggest issue according to the third seed:
Well, the hip was the problem, yeah, during the match, but it was more exhaustion.Will he have anything left? We'll see but in any case it's great news for either Andy Roddick or Fernando Gonzalez.
The physio helped me a lot, and it was a hot day. So mostly, you know, I don't think I would feel that bad today if I didn't finish that late two nights ago.
So it was quite difficult schedule for me, but ‑‑ so you can recover two times playing four hours is not easy, so I had to really put an effort in.
