John Daly will be walking his way around Royal Portrush.
The R&A in a statement released Saturday denied the 1995 Open champion's request to use a golf cart at the year's final major.
"We appreciate the difficult John is facing and have full sympathy for him as this is clearly a serious, long-term condition," the statement reads. "Having considered all of the relevant factors, the Championship Committee has decided to decline his request."
"We believe that walking the course is an integral part of the Championship and is central to the tradition of link golf which is synonymous with The Open.
