MADRID, Dec. 11 (UPI) -- Rafael Nadal, out with a knee injury since late June, is to return to competitive tennis at the end of the month in an exhibition in Abu Dhabi.
Nadal had earlier stated his intention to play in the six-player special event at year's end but until Tuesday it was unknown if his knee issue would allow it. Nadal suffered a partial tear of the patella tendon in his left knee.
