Thomas Frank admitted new signing Mikkel Damsgaard will not be fit enough to start for Brentford against Manchester United on Saturday.
The 22-year-old is expected to be included among the substitutes and could be in line for a debut off the bench.
Ethan Pinnock, Kristoffer Ajer and Sergi Canos remain on the injury list, with Canos and Ajer due to return ahead of Pinnock.

Ronaldo came on as a 53rd-minute substitute in last weekend’s home defeat to Brighton after a disrupted pre-season.
Fellow forward Anthony Martial and defender Victor Lindelof remain out through injury, with no changes to the squad from last weekend.
