Brentford defender Nico Yennaris is a major doubt for Brentford's trip to Middlesbrough.
The former Arsenal full-back picked up a thigh problem in Tuesday's development game against Colchester and is unlikely to make the long journey to Teesside.
Keeper Richard Lee (shoulder) misses out again and Sam Saunders is not ready to return despite making good progress following a niggling knee injury.
"Nico hurt himself playing in the development game on Tuesday so he's struggling, but there were no injuries from the Norwich game," said assistant manager David Weir.
"Sam is working hard. It will be great to have him because he will definitely add something when he's back, but it's important he's right."
Scott Hogan (knee) is a long-term absentee.
