Djokovic, Wawrinka to return to action in Abu Dhabi

After a poor run of form this year Djokovic retired from his Wimbledon quarter-final against Czech Tomas Berdych in July and the 30-year-old ended his season shortly afterwards due to a right elbow injury.

"The line-up is very strong as always and it will be the perfect way to make my comeback and begin the season. Abu Dhabi is an amazing place and this is going to be a great event for all of the fans," Djokovic told the tournament website.

Three-times grand slam winner Wawrinka did not defend his U.S. Open title this year and announced the end of his season in August due to a knee injury.

"The fans are amazing there and the draw is as strong as always with a lot of great players. My recovery is going well and I can't wait to be back on court," Wawrinka said.

World number one Rafa Nadal, Austrian Dominic Thiem, Spain's Pablo Carreno Busta and Canadian Milos Raonic will also compete in the tournament from Dec. 28-30.
