Norman, who has played each of the last four weeks, cited the need for his back to recover from muscle fatigue as the reason he pulled out of the season's final major.
'First and foremost I want to thank the PGA of America for inviting me to play in the 87th PGA at Baltusrol,' said Norman in a release on his web site. 'It was an honor to receive an invitation from an organization that I have the utmost respect for.'
The 50-year-old Norman played at the British Open four weeks ago and shared 60th place. He then played his first two Champions Tour tournaments, the Senior British Open and the U.S. Senior Open.
Norman finished third and fourth respectively, in those events. He teed it up last week at The International, but missed the cut.
'I knew going into this stretch that it was going to be rigorous, and I had no idea how my body would react so quickly after surgery,' Norman added. 'In conference with my neurosurgeon and physical therapist, they both believe I simply played too much too soon, hence this minor setback.'
Norman, a two-time British Open champion, is a two-time runner-up at the PGA Championship. He finished second in 1986 and 1993, with both of those PGA's being played at the Inverness Club in Toledo, Ohio.
When the 1993 U.S. Open was played at Baltusrol, the host course this week, Norman missed the cut by three strokes.
He was replaced in the field by Kevin Sutherland. The 41-year-old Sutherland's only win on the PGA Tour was a big one, as he titled at the 2002 WGC-Accenture Match Play Championship.
