Fremantle have made a big late change ahead of their clash with North Melbourne at Etihad Stadium.

Dockers midfielder David Mundy has been withdrawn from the side due to illness, with youngster Ryan Nyhuis replacing him, in what will be his debut match.

The 20-year-old was recruited to Fremantle from the NT Thunder in the 2015 Rookie Draft with the 34th pick.

Sunday's game is the first match Mundy will miss as a Docker in 2017.

North Melbourne will go in unchanged.
