Duffy's last club appearance was in November 2025, but he has now been given the chance to revive his career at Pride Park.

The Republic of Ireland international spent the 2020/21 season on loan at Celtic from Brighton, making 27 appearances for the Glasgow side. He later joined Fulham before moving to Norwich in 2023.

Duffy had been training with Derby on trial and has now signed an initial two-month contract as the Championship side contend with a number of defensive injuries.
