He has missed the last three games with a virus but was close to a midweek return at Bournemouth and should feature against the Latics.
Jennison Myrie-Williams suffered a shoulder injury following an awkward fall at Dean Court in midweek so Enoch's return will please Gary Johnson.
"Enoch is looking OK. We could have put him in against Bournemouth but we felt the extra days' rest would benefit him more and I think he'll be back," said Johnson.
Cole Skuse is rated doubtful.
"We have the likes of Craig Woodman, Bradley Orr and Liam Fontaine so we've got people who can come in and that is why a good squad is so important," Johnson added.
Simon Charlton has shaken off injury and could return to Oldham's starting line-up.
Oldham will still be without midfielder Paul Edwards (thigh), who remains sidelined for another week.
Otherwise, Sheridan has no new injury or suspension problems.
