Calderwood's successor at Northampton, John Gorman said: "It should be a great atmosphere with it being Forest, the former European champions who everyone wants to play well against, and with Colin coming back.
"We've also got some players with Forest connections so they'll be up for it. Forest have had two wins so they will be full of confidence but we're doing okay too so it should be a good game."
Eoin Jess and Chris Doig could feature for the home side against their former club.
