Novak Djokovic said he does not know if will play the grasscourt season after tumbling out of the French Open on Tuesday.
The Serb, three-time a Wimbledon champion, appeared distraught after his quarter-final defeat by unseeded Marco Cecchinato in which he was treated for neck pain.
"I don't know if I'm going to play on grass," Djokovic told a media conference room minutes after walking off court.
