LUSS, Scotland (AP) _ Fred Couples withdrew from the Scottish Open on Thursday when a back injury flared up.
Couples pulled out just before the opening round of a tournament that serves as a warmup for the British Open.
The 1992 Masters Champion is hoping to use the British Open to gain Ryder Cup points, attempting to make the U.S. team after a nine-year absence.
He ranks 12th on the points list, with the top 10 gaining automatic team places for the Sept. 22-24 matches at The K Club near Dublin.
Qualifying for the U.S. Ryder Cup team ends with the U.S. PGA Championship next month.
