RICHMOND vice-captain Brett Deledio will join Melbourne's Jack Viney in contesting his charge at the Tribunal on Tuesday night.
Deledio was initially offered a one-match ban for striking Geelong's Mathew Stokes that sparked a wild melee at the MCG on Sunday, 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.
Star Cat Mathew Stokes will be unavailable for Geelong's trip to Perth when it faces Fremantle on May 17, after accepting his one-match ban for striking Tiger Steven Morris.
Meanwhile, 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."

Docker David Mundy and Lion Luke McGuane have both accepted their reprimands.
The Fremantle star was booked for a rough conduct offence against West Coast midfielder Scott Selwood during the third quarter of Sunday's Western Derby.
The incident was assessed as reckless, low impact and body contact.

Mundy's good record, and an early guilty plea, leaves him with 70.31 carryover points.
McGuane's striking charge against Swan Jeremy Laidler in an off-the-ball clash at the Gabba on Saturday night, has attributed 93.75 carryover points with his early guilty plea.
