Novak Djokovic has revealed he will be playing in the Brisbane International, beginning Dec. 29 ... though newly-appointed coach and recently retired tennis star Andy Murray will not be in attendance.

Djokovic's new coach Andy Murray is not planning to join him for the Australian Open warm-up, Murray's team said.

Hiring Andy Murray as his coach came naturally for Novak Djokovic. On a trip to Argentina to play in a farewell match for Juan Martín del Potro, the Serbian explained why he chose his former rival after being without a coach for six months.
