World’s top-ranked men’s singles tennis superstar Novak Djokovic was writhing in pain after being struck on head by a plastic bottle as he was obliging fans in Rome with autographs following his win in the Rome Open on Friday.

Djokovic looked in pain as the bottle that reportedly slipped from the backpack of a fan in the stands struck him on the back of his head.

The 24-time Grand Slam winner was escorted from the arena on foot by security staff. While there are reports that it may have been accidental but the clips doing the round on social media don’t confirm if it wasn’t launched deliberately.

Djokovic defeated France’s Corentin Moutet 6-3, 6-1 to enter the third round where he will face Chile’s Alejandro Tabilo next.

The Serb is warming up for the French Open with a great chance to add to his array of titles at the Foro Italico, where only Rafael Nadal has won more with 10.

The top seed, who turns 37 a few days before Roland Garros gets underway later this month, easily won his first match since losing to Casper Ruud in the semi-finals at the Monte Carlo Masters.

Djokovic has made no secret in the past that he loves playing in Italy and with a clutch of big names either out injured or struggling he will fancy his chances of a record-extending 41st Masters 1000 crown.

The Rome tournament, which runs until May 19, is missing two of its biggest stars with Italian world number two Jannik Sinner and third-ranked Carlos Alcaraz both withdrawing from the men’s draw before the start.

Meanwhile clay court icon Nadal had a creaky start in the first round against qualifier Zizou Bergs on Thursday and is on the opposite side of the draw to his great rival, meaning the only way that the pair could face each other would be in an unlikely final.

One of Djokovic’s potential threats, third seed Alexander Zverev, breezed into the third round with a 6-0, 6-4 win over Australia’s Aleksandar Vukic.

And it was similar story for Djokovic, who after briefly being bamboozled by flamboyant Moutet’s array of shots slowly eased into gear, rattling off seven games in a row from 3-1 down in the first set to take control of the match.

Moutet briefly brought a smile to Djokovic and the crowd’s faces when his phone went off in the middle of an absorbing opening game of the second set, which lasted nine minutes and saw the Frenchman save four break points before giving way and allowing Djokovic to cruise to victory.
