The former Brighton and Southend striker limped out of Tuesday night's 2-0 win over Walsall in the 50th minute and will undergo a late fitness.
Jonathan Tehoue, who scored just five minutes after replacing Revell against the Saddlers, is on standby to deputise should Revell fail to recover in time.
Midfielder Jimmy Smith remains a major doubt with the hamstring problem that has kept him out of the last three games, while defender Ben Chorley could also miss out again with an ongoing knee problem.
Elliot Omozusi will continue to deputise for the latter as the Os look to extend their 12-game unbeaten run.
