Britain's Andy Murray is planning to return to the practice court towards the end of March and could be back in action before the grass-court season.
The 30-year-old, who had hip surgery on 8 January, has not played a competitive match since Wimbledon last year.
The early stages of his rehabilitation are going well, according to those close to the former world number one.
The grass-court season starts at the beginning of June, before Wimbledon begins on 2 July.
"I'm certainly not going to rush anything," Murray said immediately after his operation in Melbourne.
The Scot, Wimbledon champion in 2013 and 2016, has not played competitively since losing in five sets to American Sam Querrey in the SW19 quarter-finals last year, according to BBC.
