Albion earned a deserved point at The Hawthorns courtesy of Brandon Thomas-Asante's added time equaliser against Burnley.
Despite numerous chances throughout the night for the Baggies, it looked as though Jay Rodriguez’s first-half penalty would be enough to earn the away side all three Sky Bet Championship points.
But it was to be a debut goal for Thomas-Asante which would earn the Baggies a share of the spoils after he scrambled home a last-gasp leveller to create joyous scenes at B71.
Steve Bruce’s men face a trip to Coventry City next weekend.
The manager made one change to his starting XI, bringing Taylor Gardner-Hickman in to replace the injured Semi Ajayi.
And Albion began brightly – with Jed Wallace and Dara O’Shea sending efforts off-target and John Swift curling straight at Arijanet Muric.
The Baggies came close to netting the opener twice in quick succession around the 20-minute mark when Conor Townsend’s back-post volley was saved, and Kyle Bartley nodded the resulting corner against the crossbar.
Yet it was Burnley who took the lead. Nathan Tella raced through and was judged to have been brought down by David Button, and former Albion striker Rodriguez converted the resulting penalty.
Albion rallied and created two more good opportunities ahead of half-time, but Dara O’Shea couldn’t guide his close-range flick past Muric and Wallace smashed a finish into the post.
It was more of the same after the interval as Grady Diangana and Kyle Bartley headed crosses wide, and Muric comfortably saved Wallace’s side-footer.
Bruce turned to new signing Brandon Thomas-Asante in the midst of his team’s desperate search for a leveller.
Though Burnley struck the post in a rare breakaway, Albion threw everything at their opponents. Substitute Jake Livermore poked wide shortly after coming on before Wallace, well placed in the box, saw a shot bravely blocked by a Clarets defender.
And as it looked as though another strong performance was to yield no return for the hosts, Thomas-Asante ensured it wasn't to be the case, taking advantage of a scramble in the box before seeing his shot beat substitute goalkeeper Bailey Peacock-Farrell to create rapturous scenes at The Hawthorns.
