The Brumbies winger Chance Peni faces a suspension after being cited for alleged foul playing during the Super Rugby match against the Crusaders in Canberra.
The former Western Force player was sent to the sin-bin in the first half for a high hit on the Crusaders' Israel Dagg, who was taken from the field and failed a head injury assessment.
The citing commissioner believed Peni should have been shown a red card for the incident upon reviewing the match.
The nature of the offence is a player must not tackle an opponent dangerously.
Peni will face the SANZAAR Foul Play Review Committee on Monday.
