A 95th-minute equaliser from Jonathan Douglas earned Brentford a point at League One leaders Tranmere Rovers.
Jean-Louis Akpa Akpro's individual effort shortly after half time looked to have been enough to maintain Tranmere's 100% start at Prenton Park.
The Frenchman had headed wide from a James Wallace cross before he fired past Simon Moore from a tight angle.
But Douglas struck for the Bees in stoppage time, volleying in after Clayton Donaldson's long throw.

Brentford manager Uwe Rosler told BBC London 94.9:
"It's very difficult to say what my emotions are but we are very happy about the point.
"We were 1-0 down with 30 seconds to go and we scored.
"I think we definitely have to be very happy about that point - but tomorrow morning I think I will be disappointed."
