Ian Evatt's last-gasp header cancels out Stephen Evans' injury-time goal when a third successive victory looked certain.
Deep into injury-time, skipper Michael Dobson found Stephen Evans on the left, and having let the ball bounce once, lashed home what seemed to be the winner from fifteen yards - Griffin Park
Delight turned to despair less than a minute later when the visitors fought back. Substitute Matt Somner conceded a free-kick for a push on DeBolla just outside the Bees' area. Mark Allott floated over the cross and Evatt's header forcing its way past Julian for an unlikely equaliser. There was only time for Brentford to kick-off before Referee Mr Tomlin blew for the final whistle.
A blow then to The Bees, but a measure of the high expectations set by supporters' after two recent wins. It was a dour game, played in blustery conditions. Martin Allen kept faith with the same sixteen that returned from Hartlepool with all three points. Neither side had the wits about them to create a decent chances throughout the ninety minutes. Chesterfield "won" the first half however, racking up several corners.
Brentford were handed a let-off in the 24th minute. Spireites' winger Chris Brandon pounced on a poor back-pass from Ronnie Bull and bore down on goal. His initial shot was well saved by Alan Julian, but with an empty net in front of him, he blasted the re-bound into the side netting.
Chesterfield did score, but Evatt's header, deep into injury time, was disallowed for pushing in the Bees' penalty box.
If Chesterfield had the first half, Brentford took the second. Two efforts by Jay Tabb were off target but The Bees appeared to have the upper hand. Allen made two changes - Matt Somner and Matt Harrold replacing Stewart Talbot and Kevin O'Connor
on the half-hour mark. Veteran striker Kevin Reeves and Mark Allot tested Julian moments later, but his clean sheet remained intact.
Stephen Evans replaced Jay Tabb with ten minutes remaining and most of Griffin Park
thought he had given them three points - but Evatt had other ideas.
