Exeter are hoping experienced duo Alex Russell and Marcus Stewart will be in contention for Saturday's League One trip to Millwall.
Playmaker Russell (back) and forward Stewart (hamstring) both missed the Grecians' 1-1 home draw with Southampton through injury.
City first-team coach Rob Edwards said: "Marcus has trained for the past couple of days and he also has also got a chance of playing on Saturday. His injury is not as bad as first feared."
Joe Burnell replaced Russell in midfield against the Saints, with Barry Corr partnering Adam Stansfield in attack in the absence of Stewart
