North Melbourne forward Paul Curtis's three-match suspension has been upheld at Tuesday night's AFL Tribunal.

The Kangaroos challenged Curtis's charge of rough conduct for a tackle on West Coast's Hamish Davis during Saturday's Round 14 match at Optus Stadium.

The Match Review Officer had graded the tackle as careless conduct with severe impact and high contact. 

In Tuesday night's hearing, North Melbourne argued Curtis had laid a fair tackle in the circumstances.

After deliberating, the Tribunal disagreed and upheld the three-match ban.

Based on the club's legal team’s advice, and following significant thought given to the process, North Melbourne decided not to appeal the AFL Tribunal’s decision.

Curtis will now miss the club's next three matches against Richmond, Essendon and Port Adelaide.
