The Highlanders thought Chiefs midfielder Charlie Ngatai should have been red carded for the lifting tackle on Elliott Dixon.
All Black prospect Ngatai was yellow carded by referee Angus Gardner, who overruled the apparent TMO recommendation of a red card.
Highlanders No. 10 Lima Sopoaga noted Ngatai's remorse but quietly suggested consistency required a red card, after Highlander Jason Emery was sent off for tipping up Sharks fullback Willie le Roux a fortnight ago.
"Charlie didn't mean anything malicious...sometimes you just get in those positions," Sopoaga told Newstalk ZB's Tony Veitch.
