North Melbourne defender Jackson Archer faces three matches on the sidelines after his suspension for rough conduct was upheld.

The Kangaroos appealed Archer's ban at the AFL Tribunal on Tuesday night.

Archer was involved in a collision during Saturday night's fourth quarter which concussed Western Bulldog Luke Cleary.

The Match Review Officer charged Archer with rough conduct, grading the incident as careless conduct, severe impact and high contact.

At Tuesday night's Tribunal, the club argued Archer's conduct was reasonable in the circumstances and did not constitute rough conduct. 

The Tribunal disagreed, returning after a lengthy deliberation to uphold the three-match ban.

It is unlikely the club will appeal the decision.

Archer will now be unavailable for selection to face the Demons in the Roos' first 2025 home game, at Marvel Stadium on Sunday at 3.20pm.
