BREAKING NEWS: Rafael Nadal has withdrawn from next week's Aegon Championships at Queen's Club because of "ongoing knee problems". He says: "I have been having some problems in the past months with my knees, that's no secret, that did not allow me to compete always at 100%. I need to work with my team to recover well, work on my physical condition to be at my top form and get ready for the grass to play at Wimbledon. I hope I can be ready to compete by then."
