Reds defender Matt Carbon will miss the LDV Vans game at Port Vale as he still hasn't recovered from his hamstring injury.
The team picked up no new injuries during the Chesterfield game but Hart is likely to rest a couple of the players for the trip to Vale Park.
However, Paul Hart insisted: "It's another game we want to win but we have played a lot of games recently and I need to assess the players' reaction to that."
