John Daly has been approved to use a golf cart at next week’s PGA Championship because of arthritis in his right knee that he says keeps him from walking more than six holes.
The two-time major winner will be the first player to ride a cart in a major since Casey Martin in the US Open at Olympic Club in 1998 and 2012.
Daly is in the field at the second major of the season at Bethpage Black due to his lifetime exemption after he won the PGA Championship in 1991.
"I hope I don't get a lot of grief from the fans," Daly said.
"My knee is screwed. I had the meniscus cut out. I have osteoarthritis so bad... I can walk up a hill, I just can't walk down one."
The PGA of America said Daly applied to use a cart through its American with Disabilities Act (ADA) policy and provided "the requisite information to allow for a review of his request by the PGA's medical team".
Daly regularly plays the PGA Tour Champions, a 50-and-older circuit that allows for golf carts.
The 53-year-old withdrew from the US Senior Open last year after his request for a cart under the ADA was denied.
Daly last played a tournament without a cart last September at the Omega European Masters in Switzerland on the European Tour.
Meanwhile, the American will not play at this week's Regions Tradition, the first senior major of the year, because of illness after he suffered from dizzy spells.
The 101st PGA Championship begins on May 16, with live coverage throughout the week on Sky Sports, as Brooks Koepka defends his title.
