Andy Murray survived an injury scare before defeating Latvia's Ernests Gulbis 5-7 6-1 6-4 to reach the last eight of the Artois Championships on Thursday.

Both players struggled with their footing on a damp day at Queen's Club, and play was briefly suspended at 2-2.

And moments after levelling at one set all, Murray screamed in pain when he fell while quickly changing direction.

But after treatment to his thigh during a medical time-out, the British number one returned to seal a battling win.

Murray will next face Andy Roddick, who went through when Mardy Fish retired with an ankle injury after losing the first 7-6.
