Colin Montgomerie has withdrawn from this week's French Open citing exhaustion", the organisers said.
The eight-time European number one had planned an 11-tournament run to end at the Deutsche Bank Open, the week after the British Open, but decided to call a halt after playing in seven successive events.
He was joint runner-up in the US Open 10 days ago, double-bogeying the last at Winged Foot to finish a stroke adrift of winner Geoff Ogilvy of Australia.
Last Sunday, two days after celebrating his 43rd birthday, Montgomerie finished tied fourth in the Johnnie Walker Championship at Gleneagles, two strokes behind winner Paul Casey, having led the tournament for much of the week.
Montgomerie is already virtually assured of a place on Europe's Ryder Cup team for the K Club this September.
