Daly out of BMW PGA Championship due to hip injury
John Daly has become the fourth player to withdraw from the BMW PGA Championship, pulling out after 14 holes of the second round because of a hip injury.
The two-time major winner was 12-over par and set to miss the cut at Wentworth on Friday.
Jose Maria Olazabal (back), Paul Waring (hand) and Robert-Jan Derksen (rib) dropped out of the tournament in Thursday's opening round.
Daly's withdrawal leaves one American in the field - 489th-ranked Anthony Kang, who shot a 6-over 77 on Thursday and is battling to qualify for the weekend.
Daly is scheduled to play in the Wales Open next week at Celtic Manor, but it is unclear if the injury will rule him out.
