Sydney forward Sam Wicks has decided to challenge his four-week suspension at the VFL Tribunal after he was handed the lengthy ban for a dangerous tackle that left a Collingwood opponent with a concussion.

Wicks' second-quarter tackle on Magpies swingman Ash Johnson during last Friday's VFL meeting between the two clubs has earned the fringe Swan a charge of rough conduct (dangerous tackle).

The VFL's Match Review Panel has graded Wicks' actions as careless conduct, high contact and severe impact, leading to a base sanction of four or more matches.

Wicks and Sydney have decided to challenge the charge, declining the guilty plea option of four matches, which would see him unavailable at either AFL and VFL level for the next month.

Sydney's reserves will need a win this weekend of second-placed Footscray to keep their season alive, while the Swans' AFL side have secured their finals placing and are favoured for the minor premiership, meaning Wicks could serve his entire suspension in 2024.

The challenge could see the VFL raise the penalty to five or more matches at the Tribunal, while a standing four-game suspension will rule Wicks out of the final two rounds of the home and away season as well as Sydney's opening two finals matches.

Elsewhere, Essendon-listed ruckman Vigo Visenti has accepted a four-game suspension for a high bump on Gold Coast's Finlay Gray during Saturday's win over the Suns at Windy Hill.

The first-quarter incident has been graded as careless conduct, high contact and severe impact, offering a base sanction of four or more matches.

The suspension will see Visentini miss Essendon VFL's final home and away season game against Coburg, while the Bombers' state league side is unlikely to reach the Wildcard Round ahead of the VFL's finals series.

Visentini will also be unavailable to play in the club's two upcoming AFL games against Sydney and Brisbane, with the second half of his ban potentially served to start next year.

Lastly, Richmond VFL star Joel Garner was handed a two-game ban for a high bump on Sandringham Sebras midfielder Max Hall.

The MRP graded the incident as careless conduct, medium impact and high contact. Garner has since lodged an early guilty plea, seeing his ban lowered to one game.

The Tigers' reserves face Carlton this Sunday, with a win keeping their season alive via a likely Wildcard Round match.
