The Scot has not played competitively since last year’s Wimbledon, undergoing surgery at the turn of the year in a bid to cure his injury woes.
With Wimbledon fast approaching, Murray says he has returned to training and playing in the grass court season remains his aim.
Speaking in a video on the Guardian’s website, he said: “It’s been very slow, I’ve been out getting close to a year now which is a lot longer than I expected at the beginning.
“I’m getting closer to playing again, I’ve started training a few days ago, hoping to make my comeback during the grass court season.”
