Aberdeen boss Calderwood confirms seven cut loose
Barry Nicholson has rejected a new deal while Derek Soutar, Richie Byrne, Dave Bus, Steve Lovell, Jonathan Smith and Greg Kelly will not be offered new contracts.
"It is obviously disappointing that Barry has decided to move on but, to be honest, it did not come as a huge surprise," admitted Calderwood.
Lee Miller's future meanwhile hangs in the balance with Calderwood confirming he is 'leaving his options open.'
"These are never easy decisions to make but are necessary as we move forward and prepare for the next campaign and beyond."
