In an emotional news conference Friday, when a tearful Murray had to leave the room shortly after his first attempt to get it started, and needed to pause several times to compose himself once it had resumed, he confirmed he'd play his first-round match at the Australian Open next week but wasn't sure how much longer he could continue beyond that.
Overcome with emotion and struggling to hold back tears, the 31-year-old three-times Grand Slam champion told reporters that he had hoped to play until at least this year's Wimbledon tournament.
In an emotionally-charged press conference ahead of the first Grand Slam event of the year in Melbourne, Murray revealed that he was still troubled by the hip injury that has plagued him for the last 18 months.
"I'm in a better place than I was 12 months ago but I'm still in a lot of pain." .
Murray revealed he had spoken to his coaching team and management during training in Florida last month, and he outlined his intention to get through to Wimbledon before retiring.
Despite the limitations on his game imposed by the injury, Murray indicated he will compete at the Australian Open "but not a level I'm happy about".

"Just playing with no idea when the pain was going to stop, and I felt like making that decision", he said. "That's where I would like to stop playing, but I'm also not certain I'm able to do that", admitted Murray, who guided Team GB to Davis Cup glory in 2015.
The Scotsman broke through for grand slam glory at the US Open in 2012 before, most famously, ending Great Britain's more than 70-year men's singles drought at Wimbledon the following year.
Then he underwent hip surgery last January in Australia, not returning until June and skipping Wimbledon altogether. He also became the only player to win consecutive singles gold medals at the Olympics. "I've pretty much done everything that I could to try and get my hip feeling better and it hasn't helped loads".
"I have a severely damaged right hip", he said.
Murray said he had an option of another operation on his troublesome hip, but it was more about his quality of life after hanging up his racquet.
"The reason to have that operation is not to return to professional sport, it's just for a better quality of life". That's something I'm seriously considering.
"It got to a level where I didn't recover from that match, pushed it over the edge, having the operation would hopefully make it as good as possible".
