Referees have been asked to scrutinise the Brumbies' front-row tactics heading into the Super Rugby season after their 25-0 trial win over the Western Force in Darwin on Saturday.
The engagement is always a contentious area and former Springboks World Cup winning coach Jake White and his forwards coach Laurie Fisher dipped deep into their box of tricks to help their front three get the upper hand in the set piece.
They held a higher crouch position, dropped late and made their own call as the referee called for the engagement, causing confusion and frustration in the Force front row.
While Force coach Richard Graham did not want to comment about the way the Brumbies packed, it is understood officials at SANZAR - Super Rugby's governing body - received a complaint about the tactics.
Graham made no excuses about the loss, saying his side was "outdone" in the physical clashes and in their attitude to the game.
Hooker Nathan Charles also said the side was "out-enthused".
