Andy Murray insists his back is fine and believes the return to grass at Queen's will be less taxing on his body.
The British No.1 recently revealed he has been battling an ongoing back problem since December and seemed to struggle at the French Open.
Murray almost went out in the second round in Paris when his back went into spasm before battling his way into the last eight, where he was knocked out by Spain's David Ferrer.
The Scot leaves the clay courts behind him this week and is looking forward to starting his grass-court season at the pre-Wimbledon AEGON Championships in west London.
"It is fine," he told Press Association Sport when asked about his back. "I practised the last couple of days on the grass.
"It is probably a better surface for us; it is a bit more forgiving than the clay.
"There are a lot of long rallies on the clay, long points, long matches so the grass will probably help it a bit."
