took to the practice courts for the first time since he revealed he will retire from tennis at Wimbledon this year due to a long-standing hip injury.
Early on Friday morning, the former world and British No 1 broke down in tears in front of assembled media as he explained that his hip is continuing to cause him considerable pain and that while the plan is to conclude at Wimbledon, the Australian Open
could prove to be his final outing.
But while the pain - said to be so strong he struggles to put on socks or shoes - is not subsiding, he intends to play his opening round match at the Australian Open against Roberto Bautista Agut and so was down with coach Jamie Delgado on the practice courts to prepare.

Murray was able to crack a few smiles in the sweltering Melbourne conditions but concern grew when he winced, clutching his hip before walking back to the sidelines.
Bautista Agut is a formidable opponent inside the top 20 and with pain so prominent in his hip, Murray faces a tricky opening tie at what will be his final Australian Open in a 14-year professional career.
The Scot's mum Judy has provided a really strong support network, along with his team, in the last couple of days and she sat courtside to watch and encourage her son ahead of his Australian Open encounter.
Murray faces his Spanish opponent at the Hisense Arena and having never conceded three sets to Bautista Agut, he will hope the barren run for his opponent continues on Monday.
Having received support from far and wide after the emotional Friday press conference, Murray took to Instagram to thank everyone for their continued backing.
Posing for a selfie with his mum on Instagram, Murray wrote: 'Best way to feel better after a tough day is a big cuddle from your mum.
'Genuinely been very touched by all of the messages and support from everybody today.
'It means a lot and has made me feel much more positive than when I woke this morning. Thank you so much.'
Murray was thrashed in a practice match by world No 1 Novak Djokovic on Thursday and has not ruled out walking away from the sport if he loses convincingly to Bautista Agut in the first round.
It would bring down the curtain on one of the great British sporting careers, one that has seen him win three Grand Slams, two Olympic golds and the Davis Cup.
The announcement was met with shock and sadness from the tennis world, with former icons such as Billie Jean King and Andy Roddick calling the Brit a 'great champion' and 'absolute legend'.
Murray, a father-of-two, began his press conference by stating 'I'm not great' in a broken tone when asked how he was feeling after an 18-month battle to return to the sport.
He then became emotional and left the room for several minutes to compose himself, and on returning laid bare in heartbreaking detail how the pain in his hip meant he had stopped enjoying the sport he loved.
It seems that his dream of his daughters being able to watch him seriously compete is now, sadly, at an end.
'Obviously I have been struggling a long time and I have been in pain for about 20 months now,' he said.
'I've pretty much done everything that I could to try and get my hip feeling better and it hasn't helped loads. I'm in a better place than I was six months ago but still in a lot of pain. It's been tough.
'I'm going to play here. I can still play to a certain level, not a level I'm happy playing at. It's not just that. The pain is too much really, I don't want to continue playing that way.
'I've tried pretty much everything I could do but it hasn't worked. In the middle of December I spoke to my team and told them I can't keep doing this.'
