Defender Dean and midfielders Forshaw and Douglas were missing from the side which beat Port Vale on Saturday to rest knocks picked up over the Christmas period.
"The five Christmas games in a short period of time, with the weather and heavy pitches, our injuries are a result of that," said Warburton.
"The players will be well looked after. We will see how they shape up and how the squad looks next week.
"I have no worries. The boys that came in were fantastic."
