Brentford ended a run of five successive league defeats against Crystal Palace, but could only manage to get a point against the south Londoners in a game that won't live long in the memory.
The Bees should have had a penalty when Marc Guehi raised his hand from an in-swinging corner, but was adjudged to have been pushed by Christian Norgaard in the build-up. Vicente Guaita kept out Bryan Mbeumo before the break, and was forced to keep out a header from Pontus Jansson in the second half.
The Eagles almost stole victory at the death through Joachim Andersen, but the Dane saw his effort saved by David Raya with Jean Phillipe-Mateta almost pouncing on the rebound.
