The AFL Match Review Officer have handed down their verdicts after Round 4 of the season, with Kangaroo veteran Ben Cunnington and Hawks youngster Mitchell Lewis both receiving match bans.

Cunnington was sanctioned over a dangerous bump he laid upon Adelaide midfielder Rory Laird during their hit-out on Sunday afternoon.

The 29-year-old's bump was graded as medium impact, high contact and careless conduct, with North Melbourne confirming on Tuesday morning that they would challenge the call.

Meanwhile, Hawthorn forward Mitch Lewis will sit out next week's big game against the Demons following an incident with Docker Caleb Serong in the fourth quarter of their match on Sunday.

Lewis was charged with striking last year's Rising Star winner, with the 22-year-old being handed a one-match ban with an early plea.

Some of Lewis' teammates also were the subject of scrutiny from the MRO, with Jaegar O'Meara and Jonathon Ceglar being handed $2000 fines for striking and rough conduct respectively.

Jack Scrimshaw also received a $1500 fine for tripping Nat Fyfe during the third quarter of their showdown at Optus Stadium.

Laird was slapped with a $2500 fine for his strike on Kayne Turner, with the 27-year-old able to accept a $1500 fine with an early plea.

Finally, Demon Neville Jetta has been charged with rough conduct for a dangerous tackle on Cats star Sam Menegola during their clash at the MCG on Sunday afternoon.

The 31-year-old can accept a $2000 fine with an early plea.
