The opening quarter incident sees both players gripping each other's jumper before McCarthy's right-hand makes contact with McIntosh's chin. A free kick was not paid to McIntosh despite a field umpire's view on the incident.
While McCarthy escaped an on-field penalty, the small forward could face a nervous wait on Friday ahead of the MRO's findings from his side's 81-point win.
Given McCarthy's hit on McIntosh came away from the play of the ball, the MRO is likely to grade the incident as intentional conduct, an outcome that will increase the 29-year-old's chances of a suspension.

Clear vision of the incident shows McCarthy's hand make contact with McIntosh's head, warranting a contact grading of high from the MRO, with the level of impact likely to decide the outcome of a charge should the MRO view the incident as a reportable offence.
Even with an impact grading of low, McCarthy would receive a one-game ban if the incident was assessed as intentional conduct and high impact.
While unlikely, an impact grading of medium would see McCarthy handed a two-game suspension.
The MRO will deliver their findings from Friday's match between Brisbane and Richmond on Friday evening.
