Andy Murray has pulled out of the ATP World Tour Finals after just one match.

He got an injury in training a while ago but made it worse when he lost in straight sets to Spain's David Ferrer in London on Monday.

Andy went into the event in fine form - he's played some brilliant tennis this year - but he was way off his game against Ferrer and lost 6-4 7-5.

Andy will be replaced in the tournament by Serbia's Janko Tipsarevic, who'll play Tomas Berdych on Wednesday.
