In the dying moments of the third quarter of the Tigers' 27-point win, Mansell dived over several players to contest for the ball, seemingly hitting the back of Ginnivan's head with his forearm by accident.
The young Tiger then looked to push his arm into Ginnivan for the second time in an act that looked more scripted than the first.
The incident will see Mansell miss his side's Round 10 game against Hawthorn after the Match Review Officer charged the 21-year-old with Striking.
The MRO assessed Mansell's actions as Intentional Conduct, Low Impact and High Contact, prompting a one-game suspension that Mansell can accept with an early guilty plea.

The incident left Bews sidelined for the remainder of the Cats' win over the Giants at Manuka Stadium, with the MRO assessing the altercation.
"It was the view of the Match Review Officer that Hogan's actions were not unreasonable in the circumstances. No further action was taken," a league statement reads.
Redden can accept the sanction with an early plea, with the MRO judging the incident as Careless Conduct, Low Impact and High Contact.
