Bolton Wanderers and Crystal Palace have gone into half-time all square after neither side could break the deadlock in the opening 45 minutes.
The visitors made a lively start to the match as Wilfred Zaha found space before forcing Adam Bogdan into a smart save.
Glenn Murray then missed a golden opportunity to break the deadlock when he headed straight at Bogdan from five yards out having been found by Owen Garvan.
Zaha forced Bogdan into another save after 37 minutes, shrugging off a few tackles before shooting from a tight angle, but Bogdan kept it out with his feet.
