Britain's Andy Murray practised at Wimbledon on Saturday as he tries to prove fitness for what is expected to be his All England Club farewell.

Murray, 37, had a procedure on a back issue last weekend, leaving his participation in serious doubt.

The two-time Wimbledon champion, who plans to retire later this year, is scheduled to play his first-round singles match on Tuesday.

"I'm just trying to do what I can, trying to keep progressing each day. Whether theres enough time or not, I dont know, but Im trying," said Murray, who has been drawn against Tomas Machac of the Czech Republic.

If he does not play singles, the Scot might still be fit enough to take part in the doubles alongside older brother Jamie later next week.

Murray, who had surgery for a cyst on his spinal cord, hit for little over an hour at the Aorangi Park practice courts.

Watched by a pack of journalists and photographers in an area not open to the public, it was a relatively gentle session with his coaches Mark Hilton and Jonny O'Mara.

Murray hit forehands from the baseline and practised his serving, but did little running as he builds up slowly.

"It was alright, considering. Obviously I havent done much for the last week," said Murray, who is ranked 115th in the world.

"I need to be able to move properly, which I cant yet, so lets see in 48 hours or so."
