World No. 2 Rory McIlroy has withdrawn from the BMW PGA Championship as he continues to battle a rib injury.
"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. "It’s a disappointing decision to have to make, but I have to ensure I make a full recovery. I will now continue the process of preparing my game for the US Open and the rest of the season.
