Federer's court back in session

Roger returning to competition after long layoff

Roger Federer will make his long-awaited return to tennis after a six-month injury layoff in Sunday's mixed teams Hopman Cup in Perth, ahead of next month's Australian Open.

The Swiss 17-time Grand Slam champion has not played a match since July, when he tore up his left knee in a tumble during the final set of a loss to Canada's Milos Raonic in their Wimbledon semifinal.
