MURRAY: BACK INJURY WON'T END TITLE BID
Briton vows not to quit despite flare-up as Robson’s Wimbledon dream comes to end
WORLD No2 Andy Murray revealed he underwent extra medical treatment after his straight-sets win over Mikhail Youzhny swept him into a sixth consecutive Wimbledon quarter-final, but insists he would never dream of quitting through injury.
The 26-year-old Scot overcame the No20 seed 6-4, 7-6, 6-1, showing all his battling qualities to recover from 5-2 down in the second set, though at times he grimaced while holding his side, prompting fears he could join the grand slam record-equalling 13 players to have retired hurt in this tournament.
But Murray, who missed last month’s French Open with a back injury, says he will never succumb to pain.
“I would never stop,” said last year’s runner-up, who meets unseeded Spaniard Fernando Verdasco in the quarter-finals.
“Now that I’m playing there’s no chance I would stop, unless I couldn’t hold the racquet. My back is what it is. It’s felt way better than it was a few weeks ago. There’s no cause for concern.
“I had 20 minutes longer treatment than the last few days. But I just want to make sure that in this tournament I do all the right things. I want to take care of my body. It’s my main priority.”http://www.cityam.com/article/murray-back-injury-won-t-end-title-bid
