Merrett has been offered a three-match suspension for his sling tackle on Essendon's Michael Hurley, while Clarke has been offered a one-game ban for his late bump on Bombers youngster Elliott Kavanagh.
In contrast, Collingwood ruckman Darren Jolly is breathing easier after the MRP threw out the report laid against him for a high bump on Geelong's Mathew Stokes on Saturday night.
The panel decided that the majority of the contact was to Stokes' body and the force in the high contact was below that required to constitute a reportable offence.
Geelong midfielder James Kelly took to Twitter to question the decision to let Jolly off, likening it to his two-week ban for a bump on Bomber Brendon Goddard.
"Majority of contact to body. Within 2m of ball. No damage to player. #soundsfamiliar #missingsomething," Kelly tweeted.
North Melbourne defender Scott Thompson, who was reported during the Roos' loss to West Coast on Friday night, and Port Adelaide midfielder Hamish Hartlett are also free to play this weekend.
Merrett was booked for rough conduct, with the MRP grading the sling tackle he laid on Hurley during the first quarter at Etihad Stadium on Saturday afternoon as negligent, high contact and high impact.
The tackle resulted in Hurley's head slamming into the turf and, after failing a concussion test, he had to be subbed out of the game.
Merrett's initial sanction was a three-game ban, but this became four after his carryover points were added.
He can have the suspension reduced back to three matches if he pleads guilty.
Clarke was cited for flattening Kavanagh after the Essendon midfielder had taken a mark.
The panel graded the bump as reckless, medium impact and body contact. The initial sanction was a two-game suspension, but he can take one if he pleads guilty.
Thompson was reported for striking Eagles midfielder Matt Rosa during the second quarter of Friday night's thriller.
The MRP decided that the strike was reckless but of low impact.
Thompson's initial sanction was a reprimand and 80 carryover points, but he can escape with a reprimand and 60 carryover points by pleading guilty.
The soft punch that Hartlett delivered to the midriff of Carlton's Marc Murphy was scrutinised by the panel.
But it was decided that the force used by Hartlett was below that required to constitute a reportable offence.
Finally, four Richmond and three Melbourne players have lighter pockets after they were fined a total of $12,900 for their half-time melee at the MCG on Sunday.
