Brentford look set to be without strike trio Nicky Forster, Robbie Simpson and Carl Cort for the home game against Peterborough.
Forster underwent groin surgery a week ago and although he has stepped up his training, the clash is likely to come too soon.
Simpson is not quite ready to return after six weeks out with a hamstring injury and Cort will be out for a while yet after discovering he has a torn Achilles.
Boss Andy Scott could be tempted to stick with the side which got back to winning ways with a 3-0 success at Tranmere last weekend.
Sam Wood, Marcus Bean and Gary Alexander were recalled to the starting XI and are set to keep their places.
