Midfielders Gary Jones (hamstring) and Chris Lumsdon (foot) are set to return to full training on Thursday.
Reds physio David Moore is hopeful both will be available for selection for the the crucial Wycombe game on Saturday.
However, Steve Hayward is to have a precautionary MRI scan on his foot after an X-ray revealed no serious problems.
The experienced Hayward has been out of action since picking up the injury during the Reds 2-1 win at Brentford.
