HAWTHORN midfielder Sam Mitchell is free to face North Melbourne in Saturday's crunch game at the MCG after the Match Review Panel cleared him of striking Melbourne's Jack Watts.

The Hawks will be without young forward James Sicily, however, after he accepted a one-match ban for a late spoil on Bernie Vince that forced the Demon from the ground with a bloodied nose. 

In a mixed set of findings for the ladder leaders, superstar forward Cyril Rioli also accepted a $1000 fine for his bump on Melbourne midfielder Clayton Oliver.

Mitchell was scrutinised by the MRP on Monday, but the Panel concluded he had not struck Watts after taking the Demon to ground in a tackle. 

"Contact was made by Mitchell with an open hand in a pushing motion and it was the view of the panel there was no striking motion," the MRP said in its findings.

The Hawks remain a game clear on top of the ladder, but their poor percentage means they need to win their remaining three games or risk dropping out of the top four.

Kangaroos midfielder Jed Anderson accepted a $1500 fine for a high bump on Bulldog Lin Jong, which was graded as careless conduct with low impact to the head.

St Kilda midfielder Blake Acres was the only other player charged and on Tuesday accepted a $1000 fine for striking Carlton big man Matthew Kreuzer.

The young Saint's punch to his opponent's stomach was graded as intentional conduct with low impact to the body.

Brownlow Medal chance Luke Parker was assessed for a stray elbow to Port Adelaide forward Chad Wingard's head, but the star Swan was cleared.

"Parker tried to take possession of the ball and, as he lifted his arms, his right arm made high contact with the approaching Wingard," the MRP said. 

"It was the view of the panel that Parker's action was not reportable and no further action was required."
