And although the panel looked at five separate incidents involving Zac Dawson, including his match-day report for striking James Podsiadly, the Dockers' defender has been cleared to play in his club's first home preliminary final.
Enright was booked for striking Mayne with a round-arm to the midriff early in the second quarter of the Cats' 15-point loss at Simonds Stadium on Saturday.
Mayne was hunched over on the turf for around 30 seconds after the incident, but he soon recovered and played out the game.
The incident was assessed as intentional, low impact and body contact.
The initial penalty was a one-match suspension, but Enright can have it reduced to a reprimand by pleading guilty.
Still, Enright is unlikely to take any further part in the finals series after suffering a knee injury during the second quarter of Saturday's game. He had to be subbed out of the contest at half-time.
Mayne was booked for striking Johnson with a clenched fist to the upper body in an incident that occurred just a minute after he was struck by Enright.
Johnson fell to the ground after the contact and took some time to find his feet.
He later ran towards Mayne and remonstrated with him.
The MRP found that Mayne's strike was intentional, low impact and body contact (one point).
The initial penalty was a one-match suspension, but Mayne can have it reduced to a reprimand by pleading guilty.

The report laid against Dawson for striking Podsiadly was thrown out after the panel decided he had "used an open hand in his action and that the contact was below that required to constitute a reportable offence".
The final quarter incident in which Dawson jumped in the air and clattered into Geelong skipper Joel Selwood was also looked at, but the panel found that Dawson was making a reasonable attempt to smother Selwood's handball.
Contact between Dawson and Stokes, which occurred in the first quarter, was investigated. But the panel said that "it could not be determined conclusively that a reportable offence had occurred".
