Dawson doubt for Orient
Stephen Dawson is facing a race against time to be fit for Leyton Orient's match at local rivals Brentford.
The midfielder sustained a calf strain in Tuesday's 1-0 victory at Hartlepool and may miss out.
Ben Chorley (knee) and Jason Crowe (ankle) are both major doubts.
Both defenders have been absent since Russell Slade's side were dumped out of the FA Cup by Arsenal earlier this month.
Top scorer Alex Revell will be looking to end his nine-game scoring drought.
The former Brighton striker has hit 14 goals this season and the Os have only lost twice when he has scored.
