Albion edged closer to cementing a play-off place with a hard-earned point at Peterborough.
With the hosts battling against the drop and in need of the points, Gus Poyet’s side put in a solid rearguard action while at the other end they twice hit the woodwork.
The point extends the Seagulls’ unbeaten run to six games and up to fourth in the table – three points clear of seventh placed Bolton.
Poyet made just one change to the side which beat Middlesbrough on Saturday, with Tomasz Kuszczak returning in place of Casper Ankergren.
With Posh starting the night just a point and a place above the drop zone, they certainly started with real impetus.
Kuszczak was called into action as early as the third minute, keeping out a fierce 18-yard drive from midfielder Danny Swanson, while a dogged Albion back four made a number of blocks in and around their penalty box.
Yet Albion always looked a threat on the break, with Andrea Orlandi and David Lopez willing outlets on either flank.
Indeed, David had the visitors’ first real effort on goal, only to see his drive from outside the box fly high and wide.
Albion started to get more of a foothold in the game and came close to breaking the deadlock on 24 minutes when Matthew Upson connected with a David corner, only to see his towering header come crashing down off the underside of the bar and the wrong side of the goal-line.
Both teams then had spells of dominating possession without really threatening in front of goal – the closest Albion came was a diving Andrew Crofts header, from another David corner, while Tommy Rowe and Lee Tomlin peppered Kuszczak’s goal with free-kicks from the edge of the box.
David again tried his luck from distance, only to see his effort defected away for a corner while at the other end Inigo Calderon did well to clear a low and inviting cross from Tomlin.
Albion began to crank up the pressure again, with Dean Hammond having an effort at goal while Upson rose highest to power a header goalwards from Orlandi’s out-swinging corner.
Tomlin was proving to be Posh’s man dangerman and in the 68th minute he burst through on goal only to be foiled by Crofts. The home crowd were baying for a sending off but referee Robert Madley waved play on.
They also thought they had taken the lead nine minutes later when another low ball into the box was met by Tommy Rowe but with the goal gaping he somehow turned his effort wide.
With the game entering its closing stages Bridge drove wide and Albion thought they had grabbed a late winner when another diving header in the box from Crofts – this time from Bridcutt’s cross – cannoned off the crossbar and to safety.
