Novak Djokovic through to last 16 after injury scare

Rolling around in pain clutching his left shoulder, Novak Djokovic's Wimbledon hopes flashed before his eyes on Centre Court on Friday before he climbed off the turf to beat Gilles Simon and reach the last 16.

Leading by two sets and 3-2 in the third set, the Serb top seed was closing in on an uneventful victory against his French opponent when he stumbled and dived to reach a wide forehand, crashing heavily to the ground near the baseline. With the 2011 champion in agony and with concerned coach Boris Becker watching on, it looked as though Djokovic might be out for the count but after receiving some treatment he carried on and closed out a 6-4 6-2 6-4 win.

Despite looking a little tentative, he showed no obvious signs of discomfort and finished the job with a hefty smash. The shaken 27-year-old, who had slipped several times during a match featuring some long baseline exchanges, looked relieved at the finish and even more so later when the All England Club medical doctor gave him the all-clear.

"Luckily for me it was only an impact that had a minor effect on the joint and the muscles around, but no significant damage that can cause a bigger problem," Djokovic, who will face dangerous Frenchman Jo-Wilfried Tsonga, told reporters. "I just came from the doctor's office, had ultrasound. It's all looking good."

While arguably the best mover in men's tennis, Djokovic said he may have to practise his diving with three-times champion Becker, who virtually trademarked the art during his golden years at the All England Club. "It was obviously a scary fall. I talked with Boris. We obviously need to work on my diving volleys, learning how to fall down on the court. I'm not very skilful in that."

While he could joke about it later, Djokovic said when he felt a sharp pain in his shoulder he feared his Wimbledon might have been over. "I tried to land on my left arm. I basically had a strong impact on the shoulder. When I stood up I felt that click or pop, whatever you call it. I feared maybe it might be a dislocated shoulder."

Djokovic has not lost before the quarter-finals at Wimbledon since 2008 and while not hitting top gear so far this year, he appears to have plenty in reserve. He seemed content to trade shots from the baseline with the nimble Simon in the opening set, the two players apparently having the tennis equivalent of a staring contest as they pinged groundstrokes from corner to corner.

-Blinked First-

Simon blinked first, dropping serve to trail 4-2 but Djokovic then lost his own in the next game when his touch let him down with an attempted half-volley dropshot. Simon held serve after eight deuces in a brutal eighth game but the effort he put in to restore parity told a couple of games later when Djokovic broke again to take the opener.

The match then looked like a foregone conclusion until the late drama in the third set. Djokovic will now get the weekend to recover from his fall before playing 14th seed Tsonga, who he beat in the 2011 semis on the way to lifting the trophy for the only time.

"I think it's going to be fine," he said. "Anyway, they told me usually in these kind of particular cases you might feel soreness in the next couple of days. "But I can play around with practices and recovery and see how it goes. But I'm quite confident it's going to be all right." He will need to be firing on all cylinders on Monday against a player he says "can beat any one".

"I don't fear anything," Djokovic, who is in defending champion Andy Murray's half, said. "He's a very aggressive player. If he's on, if he feels good on the certain day, he can beat anybody really.

"Going back a few years ago, playing semi-finals against him, 2011, I remember that match well, and also the Olympic Games. I won both of the matches but I know what threat he can cause on this surface."
