Former world number seven Gael Monfils has pulled out of this month's Wimbledon tournament for "personal reasons", the French tennis federation said on Twitter on Wednesday.

The Frenchman, who beat fifth-seeded Tomas Berdych in the French Open first round, had looked to have found his feet on grass as he cruised to the quarter-finals of this week's Halle event, defeating 15th-ranked Milos Raonic in straight sets along the way.

The 26-year-old, whose career has recently been plagued by a knee injury, has climbed from 119th to 67th in the ATP rankings in a month following a series of good results including a third-round appearance at the French Open.
