League One promotion chasers Bolton held their own against Premier League Crystal Palace at the Macron Stadium in an entertaining cup tie despite a lack of goals.
Palace made a bright start as Loic Remy dragged a shot wide in the early stages but Bolton had their chances in the opening 45 minutes.
James Henry was twice denied by visiting goalkeeper Julian Speroni, before Gary Madine saw a headed effort fly just over the crossbar with around 20 minutes played.
Remy and Mathieu Flamini saw chances come and go for the Eagles and the former saw an effort hit the woodwork before the break as Palace began to take control of the game.
Allardyce brought on Yohan Cabaye for Remy at the interval and Palace dominated the ball after the restart but it was Bolton who forced the first real chance of the second half, with Henry firing wide after being picked out by Jay Spearing.
Josh Vela hit the woodwork for Wanderers just after the hour mark and Cabaye and former Bolton man Lee Chung-yong saw efforts blocked for the visitors but a replay is required to decide this third-round tie after a goalless stalemate at the Macron Stadium.
The replay will take place on Tuesday January 17 at Selhurst Park.
