New York: Rafael Nadal’s Grand Slam count will stay stuck at 11 for now, sidetracked by another knee problem.

The third-ranked Spaniard withdrew from the US Open yesterday. Tendinitis has kept him out of action since his stunning loss at Wimbledon in late June.

The injury already forced him out of the London Olympics, where he was supposed to defend his title and carry Spain’s flag in the opening ceremony.
