Bees monitoring Yennaris
Brentford will check on the fitness of Nico Yennaris before the visit of Crawley.
The young full-back, who moved to Griffin Park from Arsenal last month, made his debut in Saturday's 1-1 draw with Shrewsbury but was forced off early in the second half with a dead leg.
Winger Sam Saunders is still missing with a knee injury but boss Mark Warburton has an otherwise fully-fit squad after Harlee Dean and Adam Forshaw returned last weekend.
Defender Dean played the full 90 minutes after a month out with a groin problem and midfielder Forshaw made his comeback from a calf injury as a substitute for Yennaris and could be in line to start.
Dannie Bulman remains Crawley's only injury absentee.
Veteran midfielder Bulman suffered a fractured cheekbone against MK Dons on Boxing Day, but he hopes to get the green light to return to training next week.
Boss John Gregory will have to make changes, though, as, since their last outing, Crawley have let midfielder Nicky Adams join Rotherham, Gary Alexander move to Burton and fellow striker Emile Sinclair was loaned to Northampton.
Recent signing Gary Dicker could make his full debut in midfield while goalkeeper Ross Atkins will be on the bench after joining on loan from Derby because Johnny Maddison is suffering from suspected appendicitis.
