Sam Tillen's first Brentford goal with just two minutes remaining salvaged a point for The Bees as they drew 1-1 in east London against Leyton Orient.
Matt Heywood, who had been pushed forward as an auxiliary centre forward, got his head to a long ball forward and Tillen lashed the ball home from ten yards.
The Bees might consider themselves fortunate to leave with a point as Orient held the upper hand for large parts of the game but they were unable to kill Brentford off and Tillen's late strike earned the west Londoners a point.
Orient had edged ahead quarter of an hour in with an excellent goal; Matt Lockwood's ball forward was flicked delicately by Joe Keith into the path of Michael Simpson who lashed it home.
They could have been ahead before that, Stuart Nelson tipped a Wayne Corden shot around the post and Paul Connor shot wide from a low Gary Alexander cross.
Brentford could have pulled level when Simpson headed a Heywood flick on from a Paul Brooker corner off the line and Thomas Pinault volleyed straight at O's keeper Glyn Garner from 25 yards.
But it was Orient who had the upper hand, Connor wasted two opportunities in the first half by shooting wide and Alexander should have wrapped the game up with 10 minutes to play when he nipped in behind Brentford's defence but shot straight at Nelson, who saved with his legs.
The Brentford goalkeeper had already produced a fine save to stop a Justin Miller clearance from flying into the net from fully 75 yards.
Despite the half time introduction of Chris Moore for Calum Willock and Karle Carder-Andrews and Darius Charles also coming on Brentford offered little.
They passed the ball well at times but seemed unable to breach the home defence but Tillen's late burst into the box and fine low finish saw them break through.
And even after the equaliser Jo Kuffour could have won the game when he forced Garner into a low save.
A better chance fell to Jabo Ibhere, the Orient substitute, when he headed an Adam Chambers cross over from four yards out but he couldn't convert and the London derby finished all square.
