Pim Balkestein and Lewis Grabban have been added to the Brentford squad for the visit of London rivals Leyton Orient.
Dutch centre-half Balkestein, who had an eight-game loan spell at Griffin Park earlier this season, has rejoined from Ipswich and could go straight back into the starting line-up.
Winger Grabban will also be looking to make his debut after arriving on loan from Millwall until the end of the campaign.
The Bees are still without defenders Mark Phillips and Ryan Dickson. Centre-half Phillips has suffered a recurrence of his knee injury and left-back Dickson has a hamstring problem.
Another defender, Alan Bennett, has rejoined Wycombe on loan.
David Hunt could keep his place in midfield after being recalled for the 3-3 draw with Colchester.
John Spicer and Eric Lichaj will be added to the Leyton Orient squad.
Midfielder Spicer has signed on loan from Doncaster and American defender Lichaj was snapped up from Aston Villa.
Spicer could go straight into the starting line-up while Lichaj will be on stand-by to start at right-back if captain Stephen Purches fails a late fitness check.
Purches missed last weekend's defeat by Huddersfield with a calf injury.
Goalkeeper Jamie Jones has recovered from the back injury which ruled him out against Walsall a fortnight ago but he only made the bench last Saturday with Glenn Morris keeping his place.
Romanian striker Adrian Patulea staked his claim for a recall with five goals for the reserves on Wednesday.
