Leon Legge headed a 94th minute equaliser as Brentford earned a share of the Boxing Day spoils against AFC Bournemouth.
Charlie Sheringham's first half goal looked as if it would be enough as the game ticked in to its final seconds.
But they failed to clear a long throw and Jake Bidwell set up Clayton Donaldson to put over an inch perfect cross and Legge headed powerfully in.
The visitors had taken the lead just before the 20 minute mark and rarely looked like relinquishing it.
They kept Brentford largely at arms reach and when The Bees could breach the well organised defence, protected by a five-man midfield, they couldn't get past Darryl Flahavan in the Bournemouth goal until Legge's last gasp header.
It took about 15 minutes for the game to get going.
Little happened of note in the early stages although a low Sheringham shot, kept out well by Richard Lee, was a sign of things to come.
As was the way Bournemouth were able to keep Brentford at bay, using the additional man in midfield to fine effect.
Brentford could have taken the lead when a Sam Saunders free kick eluded three or four men and bounced in to the arms of Flahavan.
Sheringham was unable to convert a superb cross from the overlapping Charlie Daniels and from a similar move a few minutes later, Bidwell made a fantastic headed clearance to stop Wes Fogden finishing at the far post.
Niall McGinn forced a low save out of Flahavan after running from deep and shooting.
Bournemouth took the lead just before the 20 minute mark in slightly controversial circumstances.
Simon Francis lifted a ball over the Brentford defence and Sheringham, possibly in an offside position, brought the ball down and finished well from an acute angle.
Bournemouth seemed content to sit on that and the rest of the first half was played without the visitors really threatening to create.
But Brentford now had a ten man wall to try and breach and they were not able to create many openings.
They could have levelled within minutes when a long throw was half cleared, Donaldson curled a ball over and Gary Alexander headed against the outside of the far post.
Alexander and Donaldson both flicked a Bidwell cross wide and Saunders curled a free kick in to a defensive wall before half time but the visitors went in at the break ahead.
The game became stretched in the second period - Brentford began to put more bodies forward and that left gaps for Bournemouth.
Flahavan got to a Donaldson knock down just before Alexander seconds after the re-start before Saunders curled a free kick wide and then had a volley blocked.
Substitute Lyle Taylor missed the target with an overhead kick before, after Brentford had failed to clear a cross from the right, Shaun MacDonald hit the outside of a post with a low shot.
MacDonald had another effort deflected wide soon after before Jonathan Douglas missed the target with a snap shot.
Flahavan kept out a Saunders effort following good work from Alexander and Donaldson and substitute Myles Weston saw a shot deflect wide while, at the other end, a Taylor header was easy for Lee.
The visitors had chances to wrap it up - Lee got down well to keep out a Fogden strike and Taylor narrowly missed the target with a curling shot.
Harlee Dean blasted well over from distance and then flicked a header wide as Brentford tried for an equaliser.
It looked as if they would not find one, particularly when Flahavan kept out a Donaldson volley, but Bournemouth could not clear the resulting throw and Legge pounced.
