Britain's Andy Murray says he plans to retire after this year's Wimbledon but fears next week's Australian Open could be the final tournament of his career.
The three-time Grand Slam winner, who is struggling to recover from hip surgery, was in tears as he spoke to journalists in Melbourne on Friday.
"I'm not sure I'm able to play through the pain for another four or five months," Murray said .
"I want to get to Wimbledon and stop but I'm not certain I can do that."
31-year-old Murray says he still intends to play his Australian Open first-round match against Spanish 22nd seed Roberto Bautista Agut next week.
The former world number one had surgery on his right hip last January and has played 14 matches since returning to the sport last June.
