Norwich City signing Ryan Bennett won't move to Carrow Road until next month.
Bennett will also stay at London Road on loan until the end of this month while Posh boss Darren Ferguson looks for a replacement.
"It feels like I'm still a Peterborough player and I'll continue to play as I have been and try not to think about the move I've got now.
"It's up to me to go out there and play well for the next month because a lot of people are going to be looking at me thinking 'Is his head there?' It's up to me to prove that it is.
"Peterborough is a club I've really come to love. But it's a move I couldn't turn down.
"I'm sad to go but it's something I had to do.""I don't think it's sunk in yet really," Bennett told The Posh Player.
