World No 1’s knee discomfort has returned ahead of the PGA Championship warm-up event
Johnson, whose Masters title defence ended in a missed cut last month, said his decision to withdraw from the 13-16 May AT&T Byron Nelson in McKinney, Texas came after the knee discomfort he occasionally experiences returned.
“After consultation with my team and trainers, I feel it is best that I remain at home and focus on my rehabilitation work,” Johnson said in a statement.
“I am not pleased about this situation, as I was really looking forward to playing this week.”
Johnson has competed twice on the PGA Tour since his unsuccessful Masters title defence, earning a share of 13th place at the following week’s RBC Heritage followed by a tie for 48th at the Valspar Championship.
The PGA Championship, which is the year’s second major, is 20-23 May in Johnson’s native South Carolina at Kiawah Island Resort’s Ocean Course.
