Paris - Gael Monfils will miss France's Davis Cup quarter-final against the United States because of an abdominal injury on his left side.
The French tennis federation said Monday that coach Guy Forget will soon name his replacement for the 25-year-old Monfils for the contest at Monte Carlo Country Club, which starts on Friday.
Monfils - who is 14th on the ATP rankings - started experiencing pain during practice on Sunday and a subsequent MRI test turned up a lesion on his left oblique muscle. He will need to rest for 15 days.
The French team includes Jo-Wilfried Tsonga, Julien Benneteau and Michael Llodra. The US or France will face the winner of the quarter-final between Spain and Austria.
