Doncaster defender Byron Webster will not be rushed back into action as he recovers from a broken bone in his foot.
Webster, sidelined since January with an elbow injury and then a fractured metatarsal, had been hoping to make a timely return to action following news of Wayne Thomas's knee injury.
But manager Sean O'Driscoll said: "He's found it difficult just coming back into training. You can do all of the work you want to in the gym, but it's difficult to come back into it.
"Rather than pushing him, he's having one day on and one day off and if he gets no reaction, then we will push him on as quick as we can.
"He's got this one awkward spot which we're trying to manage. We don't want to go down the road of having another operation to solve it."
