Former DDFUA Umpire Brett Rosebury will officiate in his 204th AFL match on Saturday when Adelaide play Fremantle at AAMI Stadium.

He will break the record for most AFL games by a West Australian held by field umpire Grant Vernon and boundary umpire Jamie Giles.

This will also mark Brett's 100th consecutive AFL match.

Brett will be joined by fellow West Australian umpire Dean Margetts to mark the occasion.
