Here are the North End player ratings from the clash in which interim head coach Frankie McAvoy suffered a first defeat of his tenure.
9. Tom Barkhuizen 5
Kept busy on both sides of the pitch delivering his long throws. Caught out for Brentford's first goal. Ended-up at left-back which isn't his position. Photo: Camerasport
10. Ched Evans 5
Got little joy up front and looked dead on his feet when he was subbed late on. Photo: Camerasport
11. Emil Riis 6
Had a couple of sights of goal in the first half and was a touch unfortunate to be substituted early in the second period. Photo: Camerasport
12. Alan Browne 5
Part of a triple substitution in the 53rd minute. Didn't get into the game as Brentford took control. Photo: Camerasport
