Manager Nigel Adkins has given an update on injuries to a number of key first team players.
He hopes Jobi McAnuff and Nick Blackman will be available for midweek, but is less hopeful on Royston Drenthe and Danny Williams making the trip to Barnsley.
He said, "Jobi trained for the first time on Friday, then on the pitch after the game on Saturday so we're delighted with that and all being well he comes into contention for the next two games.
"Hal got a bit of cramp late on against Birmingham, Garath has a nasty gash on his ankle so he had to come off as well.
"Nick Blackman had a swollen knee in the week, I'd like to think he will be somewhere near [being available] come Tuesday.
"Royston and Danny have foot injuries, I'm not sure about them [for Tuesday]. I've got to make sure with tough games that everyone is as fit as possible.
"Ledge is on the pitch as well, I'd love to see if we can get him an under 21 game in the next fortnight, he's a top, top man. He's been working so hard."
On Saturday Jem Karacan confirmed he will be out for a number of months with a knee injury, while striker Jason Roberts continues to work back from a hip injury.
