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.
'He hasn't played or trained with the team for the last 10 days,' Frank said.
'That's not to say he can't play 10, 15, or 20 minutes at a good level for this game. He is not ready to start. He had an absolutely perfect medical with nothing to worry about.
