John brought the biggest cheer of the day at Reading when he was replaced by Patrick Suffo and has told City supporters to lay off him.
The City boss said: "With the game on Saturday in mind, I’m leaving Stern John out to get some training. 'I think it would be better for Stern and I think it would be better for us as a football club.
'We’ve got some more of the lads in the squad – Craig Pead’s in there as is Gary McSheffrey, Neil Wood and Eric Deloumeaux so we’ve got options.
'When you are getting so many games in such a short period of time I think sometimes it’s better to make those decisions.'
