Jimmy Calderwood spoke to RedTV at lunchtime.

"The team news is that Lee Miller is out through suspension, Derek Young and Darren Mackie are both out injured. Both are a bit of a concern as we thought they would be back by now and we are just trying to get to the bottom of the problems - both hamstring problems. Lee Miller will be back next week though. Zander Diamond is of course out for the season. Jamie was back training today so there is a chance he could be back as early as next week, we will just see how it goes though as obviously don't want to push any of them.

"We have absolutely nothing to lose because we have to go out and go for it. We were very disappointing at Celtic Park and hopefully we will get back to how we played against them the two times previously this season. I think Kerr being back for us is very important because he brings with him the energy levels and skill that we really have missed without him, he urges people on and gets everyone going which is a welcome return. I hope we see the Aberdeen we know and not the one we saw last week.

"We are actually on more points now than we were at this stage last season but it doesn't feel like that because of the inconsistency and that is what disappoints me.

"I think they will miss Scott Brown because he is such a great player and is always driving forward and I think we missed Kerr in the same way but I'm sure Celtic have the manpower to cope without one of their top players.

"It is an absolutely massive game for us and if were to get the 3 points and Hearts were to lose at Ibrox then the gap would only be 3 points and Hearts have still to play up here. We have some unpleasant headaches in our team selection and this is going to make for an extremely young bench but if we can play like we know we can then there is no reason we can't take something from the game."
