Richmond and Hawthorn will contest decisions by the AFL Tribunal at the league's Appeals Board after following separate charges of rough conduct were handed down on Tuesday night.

Tiger Rhyan Mansell faced the Tribunal after being charged by the Match Review Officer with a minimum three-game suspension for his hit on Fremantle's James Aish during Saturday's clash with the Dockers.

The MRO referred Mansell directly to the Tribunal, who upheld the charge after Richmond pleaded not guilty to rough conduct.

The Tribunal found that Mansell was in a "bumping action" when he collided with Aish, who suffered a concussion and could miss multiple matches as a result of the incident.

The Jury also found that Mansell was not contesting the ball.

"Although he approached the contest at speed, the vision shows that from a metre or two from the point of impact where Mansell bumps Aish, that this was not simply a reflexive or involuntary bumping into an opponent. It was a bump," Tribunal chair Jeff Gleeson said in his summation of the case.

"The question then arises as to whether Mansell was contesting the ball. We find that he was not. Again from a metre or two prior to the collision he turned and his hands were not reaching for the ball."

Richmond confirmed on Wednesday afternoon that they would appeal the Tribunal's verdict and take the matter to the AFL Appeals Board, which is likely to commence on Thursday evening.

Mansell's three-game suspension sees him miss upcoming matches against St Kilda, Brisbane and Sydney, with a return scheduled for Round 18 against West Coast.

Hawthorn will also head to the Appeals Board after James Sicily's charge for rough conduct was also upheld, with the Hawks also pleading not guilty to the charge, contesting the grading of careless conduct.

The Tribunal found that the outcome of Sicily's tackle on Brisbane's Hugh McCluagge would not have been significantly altered by teammate Tyler Brockman's influence on the contest.

"Sicily kept clinging on to McCluggage and kept rotating him. We do not accept that Brockman's involvement caused an otherwise safe tackle to be dangerous," Gleeson said.

"Sicily continued to rotate McCluggage, pulling down on his left arm and pinning his left arm, causing this tackle to be dangerous. He could have released the left arm, had he done so McCluggage would not have been rotated across his body and into the ground with such force.

"Accordingly, we find this was a dangerous tackle."

Hawthorn have confirmed that Sicily's Appeals Board case is set to be heard on Monday, June 19 as the club is scheduled for a Round 14 bye.
