Rory McIlroy is heading back to the sidelines with the same rib injury that held him out of competition for seven weeks earlier this year.
McIlroy's injury flared up at The Players, but despite finishing in a tie for 35th at TPC Sawgrass, he has withdrawn from next week's BMW PGA Championship at Wentworth, where he won in 2014.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.
