Dean Pees has said that Chuck Pagano will not recognise everything that the Baltimore Ravens defense does this weekend.
The Indianapolis Colts head coach was previously the defensive coordinator for the Ravens.
However, the current defensive coordinator told the Ravens' website: "I think there are enough changes that there will be some things there that he might not recognise.
"They're going to get a program out to figure out who is lined up where, as sometimes I do."
The two teams face each other in the playoffs on Sunday.
