Manager Expects Tough Test At In-Form Posh
Micky also confirmed that Zak Whitbread and Ian Black both trained on Thursday morning and will be available for selection on Saturday.
"It has just been cancelled out of professionalism," said Micky.
"Fair play to the players- they deserve credit because they came to me and said that the party is cancelled as we have an important game.
"As far as I’m concerned, I think everybody should have a Christmas party. Christmas is to be celebrated.
“It will be rearranged for another day.”
The Shrewsbury Town squad was set to have their Christmas party on Saturday night, but Micky confirmed that the players have decicded to cancel that event for now due to the FA Cup replay with Grimsby taking place on Tuesday.
"Skitty (Chris Skitt) managed to push his nose back into place during the game so he’s going to be alright," said Micky.
"It was a bit frightening but Skitty and the club doctor have done a great job.
"He should only be out for a couple of weeks so it is not as bad as we first feared. We’ll just let time take its course and do what we have to do."
But Micky insisted that the 26-year-old will not be out of action for as long as expected.
Goalkeeper Jayson Leutwiler sustained a severe facial injury in Monday night’s goalless draw at Grimsby Town in the second round of the FA Cup, breaking his nose and suffering concussion.
"Peterborough are playing terrific football and are in a good position in the league," said Micky.
"It will be a tough game but we’re looking forward to the challenge.
"They’re all tough, I keep saying that every week.
"I can’t tell you that there has been an easy one- we’ve just got to make sure we’re ready."
Graham Westley's Peterborough have won their last six games in all competitions, meaning Micky knows the task his side face at the ABAX Stadium.
