Ben Crane withdraws from US PGA Championship with back problem

Ben Crane is the second golfer to withdraw from the US PGA Championship after feeling back pain ahead of round two at Valhalla.

Yesterday, defending champion Jason Dufner was forced to walk away from the tournament due to a neck injury.

Crane, who hit a three-over 74 in his first round in Kentucky, has now withdrawn from his second tournament in a row after being forced to walk away from Firestone last week.

Ryan Palmer is currently at the top of the leaderboard at seven-under through nine after rain halted today's play.
