The 31-year old Scot hopes to make it through to Wimbledon in June, but admits his body may force him out the sport earlier.

"I'm not sure I'm able to play through the pain for another four or five months," he admitted through tears today. 

"I want to get to Wimbledon and stop but I'm not certain I can do that."

He has pledged to play in the Open next week with a first round match against Spanish 22nd seed Roberto Bautista Agut.

But 2016's world number one is still trying to over come surgery on his hip last January and has only played 14 matches since he returned from the operation in June.

He added: "I'm not feeling good. I've been struggling for a long time.

"I've been in aI've pretty much done everything I could try to get my hip feeling better and it hasn't helped.

"I'm in a better place than I was six months ago but I'm still in a lot of pain. I can still play to a level...but not a level I have played at."
