“I have been sick overnight as a result of eating some bad food,” said Monfils, the World No. 18.
“I don’t have any energy, my head feels heavy, my nose is blocked up and I was sick three or four times. I probably got about one hour’s sleep last night.”
Monfils has been sidelined due to a hand injury since competing at the BNP Paribas Masters in Indian Wells.
“The past couple of months have been more than bad luck. All journalists know I like playing on clay courts and wanted to have good preparation for Roland Garros. I hope I’ll be back on the court soon.”
