Murray will play through pain

MADRID - Andy Murray was hoping that a jolt to his chronically weak knee would not prevent him from continuing at the Madrid Masters after defeating Marin Cilic 7-5, 7-6 (7/2) on Thursday

The Scot fourth seed reached the quarter-finals after trailing 3-5 in the first set against the Croatian

Murray said he will hope to make his Friday match against either Andy Roddick or Gael Monfils

"As long as the pain is bearable, I'm ready to play," said the US Open finalist

Murray's knee is subject to injury due to his specific bone plate, a problem which has bothered him throughout his career

"The important thing is to make sure I deal with it properly.”
