Geelong key forward Tom Hawkins will face the AFL tribunal after being referred directly for intentional umpire contact.
It will be a test case, with Hawkins saying his contact with field umpire Dean Margetts was accidental.
Cats coach Chris Scott said after Friday night's match he hoped common sense would prevail.
AFL match reviewer Michael Christian also offered Hawkins a $2000 fine for rough conduct against GWS defender Nick Haynes.
The Giants' Adam Tomlinson was also offered a $2000 fine for rough conduct against Jed Bews.
Hawkins was in outstanding form, with four goals in Geelong's 61-point belting of the Giants.
He appeared to push Margetts' hand away after he had a free kick and a 50m penalty paid against him for driving his knee into Haynes' backside.
Margetts can be overheard on the Seven Network broadcast warning Hawkins not to touch him.
"I actually thought initially it was an opposition hand so I didn't mean to make any contact," Hawkins told Seven.
"I apologised to him after .. (it was) obviously accidental.
"That's what happens in footy ... heat of the moment."
Scott felt the fact Margetts didn't pay a secondary 50m penalty after Hawkins brushed his hand was telling.
"It's a good observation that the umpire was really clear that it didn't even warrant a further 50," Scott said.
"If he had a problem with it he would've paid another 50. So I think that part's pretty clear, isn't it. Common sense should take over at some point."
The Cats improved to a 4-3 record after a win in which they had contributors across every line.
Mitch Duncan (33 disposals), Joel Selwood (25) and Tim Kelly (30) led the way in the middle, while Tom Stewart and Jack Henry were in everything down back.
Patrick Dangerfield spent plenty of time inside the attacking 50 and finished with 27 touches and two goals.
"It was a pretty complete (performance)," Scott said.
"Our senior players were disappointed with their performances in some of the fundamentals last week (in the loss to Sydney) and were determined to turn it around.
"They were instrumental in the planning and preparation for this week.
"I came to the ground with great confidence because when our senior players have that attitude they generally deliver."
