(Reuters) - Gael Monfils suffered yet another injury as he retired from his third-round match against Belgian ninth seed David Goffin at the U.S. Open on Saturday.
The Frenchman had dropped the first set 7-5 before losing interest in the match in the second as he appeared to suffer from a leg injury.
The 18th seed quickly fell 5-0 behind, finally requesting the trainer on court for a right thigh massage. He won one game before throwing in the towel.
Monfils has suffered an Achilles injury, a knee injury and an ankle injury this season.
Goffin next faces Bosnian Damir Džumhur or Russian Andrey Rublev for a place in the last eight.
