New-signing Brandon Thomas-Asante clinched a last-gasp equaliser for West Brom on Friday to deny Burnley going top of the Championship at The Hawthorns with a 1-1 draw.
Jay Rodriguez had appeared to break the hearts of his old club, who dominated the game and hit the woodwork twice and missed numerous other chances.
But Thomas-Asante, signed from Salford for STG300,000 ($A507,000) in the transfer window, popped up to earn a richly-deserved point.
Defeat would have added more frustration for West Brom manager Steve Bruce, who was no doubt still fuming after seeing two deadline-day transfers fall through after documents failed to arrive with the EFL in time.
The Baggies had tried to sign Fulham midfielder Josh Onomah on loan and Brighton midfielder Steven Alzate but both fell through.
West Brom wasted numerous chances in a dominant first half only to trail at half-time.
Jed Wallace fired an angled rising drive over the bar from 12 yards after he started the move before Taylor Gardner-Hickman's cut-back.
Captain Dara O'Shea then headed over the bar after meeting Wallace's corner at the far post, before John Swift curled a shot straight at goalkeeper Arijanet Muric.
There was brief respite as Rodriguez glanced a header straight at David Button.
But the hosts returned to the attack as Conor Townsend's far-post volley forced Muric to scramble around the post before Kyle Bartley headed Wallace's corner against the top of the bar.
Burnley's tactic of hitting Albion on the break threatened to succeed when the dangerous Nathan Tella picked up a loose ball, but his half volley from the edge of the box flew a few yards wide.
On-loan Southampton striker Tella was suddenly a huge threat to Albion, winning a penalty after latching onto Muric's long kick only to be brought down when Button's right foot caught his left instep.
Rodriguez coolly sidefooted home from the spot to give Burnley a 30th-minute lead, scoring his fourth goal of the season.
After the break, Wallace wasted yet another chance for Albion after scuffing his effort straight at Muric from Townsend's cross.
Against the run of play, Burnley substitute Darko Churlinov hit the post after a woeful Townsend header back towards his goalkeeper let the Clarets player in.
Thomas-Asante equalised in the eighth minute of time added on when he scooped home after Swift's free-kick had been scuffed across goal by Burnley defender Connor Roberts.
