Nadal will return for Abu Dhabi exo

Former world No. 1 star Rafael Nadal will return to action for an exhibition event in Abu Dhabi at the end of this month.

The 11-time Grand Slam champion has been sidelined with a left knee injury and hasn't played since a shocking loss against unheralded Czech Lukas Rosol in the second round at Wimbledon in June. He missed the Olympic Games, U.S. Open and season-ending ATP World Tour Finals because of a partial tear of the patella tendon in the knee.

The 26-year-old Nadal is the reigning French Open champion and has captured Roland Garros an Open Era-record seven times.

Abu Dhabi is a six-man tournament that will commence December 27 and also feature current world No. 1 star Novak Djokovic and Olympic and U.S. Open champion Andy Murray.
