Viney was sent straight to the Tribunal after being charged by the MRP with engaging in rough conduct against Adelaide's Tom Lynch during the first quarter of last Saturday's game between the Crows and the Demons.

Deledio was initially offered a one-match ban for striking Geelong's Mathew Stokes

, but the club has opted to challenge the ban.

If unsuccessful, Deledio is looking at a two-match sanction, and the first suspension in his 198-game career.

Melbourne coach Paul Roos promised his club would vigorously defend Viney – whose case was sent directly to the Tribunal – in Tuesday's hearing.





"Given it's a tribunal matter I don't think I can say anything, but we'll defend it vigorously," Roos said on Fox Footy's AFL 360.





"We've had a really good look at it.





"We believe Jack is actually bracing for contact because there's two guys coming the other way."
