For the second time this year, Rory McIlroy will miss tournament time due to a rib injury that he first suffered when testing equipment and that he aggravated while preparing for last week's Players Championship.
McIlroy, 28, withdrew Friday from next week's BMW PGA Championship in England, the European Tour's flagship event and one the Northern Irishman won in 2014.
"Having had a reaction to my earlier rib injury, I have been advised to take a conservative approach to my recovery which unfortunately means I have to withdraw from the BMW PGA Championship next week," McIlroy said in a statement released by the European Tour.
