Andranik Teymourian, Rob Kozluk and Anderson De Silva all suffered problems in the goalless draw with Derby, a game that winger Adam Hammill missed through injury.
"Both (Andranik and Anderson) trained this week and so did Rob. Adam has been in the gym training and he should be fit for the Notts Forest game.
manager Simon Davey told the Sheffield Star
"Kayode (Odejayi] has come back from loan and he's now part of the group, and Diego Leon's also back training.
"We need to keep picking up points in every game, so it's important we have as many players available as possible."
