SHEBOYGAN, Wisconsin (AP) — John Daly will not return to finish his second round at the PGA Championship because of a shoulder injury.

Daly notified organizers late Friday night that he would not be back Saturday. He was 5 over at the seventh hole in his second round. He shot a 76 in his opening round Thursday.

Daly was in a group with Padraig Harrington and Davis Love III.

The 44-year-old Daly won the 1991 PGA Championship, earning a lifetime exemption to the event. He either hasn't made the cut or withdrawn in 13 of the 17 appearances since his victory, never finishing higher than 32nd.

A five-time winner on the PGA Tour, his best performance this year was a share of 24th at the Puerto Rico Open.
