The AFL tribunal has carte blanche to punish Dale Thomas on Tuesday night, with the Carlton veteran alleged to have called a boundary umpire a "f---ing cheat" during Sunday's loss to Greater Western Sydney.

Thomas has been directly referred to the tribunal following a match-day report for umpire abuse, in which he is alleged to have stingingly questioned the integrity of boundary umpire Michael Barlow during the third quarter of the Blues' heavy defeat at Giants Stadium.

It is not suggested that Thomas' comments were in any way based in fact.

Because of the nature of the charge, Thomas is unable to take an early guilty plea, with the tribunal jurors given free rein to deal with the unusual charge as they see fit.

Sydney co-captain Dane Rampe was last week fined for inappropriate comments directed at an umpire, but that matter had been diverted to the AFL's football operations department, as opposed to the tribunal.

"I certainly felt, in discussions with [AFL football operations chief] Steve Hocking, it was a serious enough breach that it should be sent and heard by the tribunal," match review officer Michael Christian said of the Thomas incident on Monday.

In other match review news, Collingwood forward Travis Varcoe was cited for a high bump on Saturday.

Varcoe was handed a one-match ban after he cannoned into both Phillips brothers – St Kilda's Ed and teammate Tom – in a contest and struck Ed Phillips high.

Christian assessed the conduct as "forceful front-on contact" that was careless and high, with medium impact.

It is unknown if Collingwood will appeal the decision.

However, GWS big man Shane Mumford has escaped sanction for his hit on Carlton's Marc Murphy.

Murphy was on the ground competing for the ball when Mumford arrived from the side and collided with the former Blues skipper.

Murphy was taken to hospital after the incident and stayed in Sydney overnight, having sustained broken ribs.

The match review officer said Mumford's actions were not unreasonable in the circumstances and no action was taken.

"That was obviously looked at very closely. Shane came in to apply pressure to Marc Murphy. Contact was made with his upper right thigh to Murphy's midriff. Simultaneously on the other side of Murphy, Josh Kelly also made contact to Murphy's midriff, effectively jamming him up between the two players," Christian said.

"So when it was all said and done, the question was: '[Were] Mumford's actions careless or unreasonable in the circumstances?' The decision was made that his actions were not unreasonable in the circumstances."

Blues skipper Patrick Cripps was fined for striking Jeremy Finlayson, while Giant Tim Taranto was charged with misconduct against Cripps and also fined.

Richmond ruckman Ivan Soldo was offered a one-match ban for striking Hawthorn's James Worpel in an off-the-ball incident, while Tigers star Tom Lynch was fined, also for striking, in an incident with James Sicily.

The Tigers are expected to fight the Soldo ban, which has left Richmond's ruck stocks further depleted given Toby Nankervis is injured.

Brisbane's Rhys Mathieson was charged with striking Adelaide's Jordan Gallucci and offered a one-match ban.

Sydney's Luke Parker and North Melbourne's Marley Williams were both fined for striking.

The AFL, meanwhile, admitted that a decision to award West Coast's Lewis Jetta a free kick in an incident that left Melbourne's Tim Smith concussed was incorrect. Jetta has accepted a one-match suspension for the incident.
