By AP Feed FoxSports Oct 2, 2012 at 1:00a ET Rafael Nadal plans to return from a knee injury at an Abu Dhabi exhibition tournament in December. Organizers of the Mubadala World Tennis Championship said on Tuesday in a statement that Nadal is set to join a field including Novak Djokovic, Andy Murray and David Ferrer. The tournament runs from Dec. 27-29. Nadal hasn't played since losing in the second round of Wimbledon in June. He is recovering from a partially torn patella tendon in his left knee. The 11-time Grand Slam champion said last month he had no timetable for his return and was targeting the Australian Open in January for his return to competitive tennis.
