Brentford full-back Henrik Dalsgaard will not be fit in time for Monday night’s west London derby with QPR.
Dalsgaard has missed the last three Bees matches after picking up a heel injury against Birmingham earlier this month.
The Denmark international also sat out his country’s World Cup play-off games with the Republic of Ireland.
Josh Clarke, who scored in Brentford’s 2-0 win at Loftus Road last season, is again likely to deputise.
Brentford boss Dean Smith has reported an otherwise clean bill of health in his squad.
