COLEMAN Medal leader Jarryd Roughead has accepted a one-match suspension from the Match Review Panel for tripping Melbourne's Dom Tyson.

Roughead, who will miss Hawthorn's big clash with Fremantle at Patersons Stadium on Sunday, was the only player to cop a penalty from the MRP after its review of round 20.

He would have escaped with a reprimand if not for the 64.06 carryover points that were added to his record after he was found guilty of rough conduct on Sydney Swans forward Ben McGlynn following round eight.

Hawthorn has opted to accept the ban in part to clear Roughead of carryover points heading into the finals.

WATCH: Hawthorn explains their decision not to head to the Tribunal

Geelong star Steve Johnson is in the clear after the contact he made with his boot to the head of Fremantle's Lachie Neale was deemed not worthy of a report.

Cats midfielder Travis Varcoe is also free to play in Friday night's clash with Carlton after the scuffle he had with Dockers defender Nick Suban was given the all-clear.

Two other incidents were scrutinised.

The panel found that Fremantle star Nat Fyfe had no "realistic alternative way to approach the contest" in which he accidentally made contact with his knee to Geelong defender Andrew Mackie's head.

The contact resulted in Mackie spending 20 minutes on the bench during the third quarter while he underwent a concussion test, although he later returned to the field and played out the game.

The MRP also cleared Brisbane Lions defender Justin Clarke of any wrongdoing after the tackle he laid on Adelaide's Tom Lynch ended with Lynch being taken to hospital for scans on his neck.
It was found that Lynch ducked into the tackle at the last second and there was nothing Clarke could reasonably do to avoid the contact.

There was no such good news for Roughead, who stuck his leg out and tripped Tyson after the Demons midfielder changed direction in an attempt to get around him.

The MRP graded the incident as reckless, low impact and body contact. 

His initial penalty was 80 demerit points and a reprimand, but his carryover points increased the total to 144.06. 

By pleading guilty, he reduces the sanction by 25 per cent to 108.05, just over the threshold for a one-match suspension.
