John Daly, who won the PGA Championship in 1991, has withdrawn from this week's major at Oak Hill in Rochester, N.Y., and will be replaced in the field by Stephan Jaeger.
Daly, 57, withdrew due to injury, although no details were disclosed about the nature of the injury.
Daly becomes the third former champion to withdraw from the event, joining Martin Kaymer (2010) and Jason Dufner (2013).
Daly has been a mainstay at the PGA Championship, having only missed one of the last nine events (2020).
Daly played this past weekend on the Champions Tour, finishing T65 at the Regions Tradition.
The PGA Championship tees off Thursday at Oak Hill's East Course.
