St Kilda’s Ben Long could be facing a month-long suspension after his bump on Fremantle ruckman Sean Darcy was referred straight to the AFL tribunal.

Darcy was bending over a loose ball when he copped a fierce hip-and-shoulder from Long in Fremantle’s six-point win on Saturday.

The Fremantle big man was concussed by the hit and is no certainty to play in next Sunday’s western derby against West Coast.

The incident was assessed as careless conduct, severe impact and high contact, and will now be judged by the AFL Tribunal.

North Melbourne great David King has urged the AFL to make a stand by banning Long for four matches.

Essendon star Dylan Shiel was offered a two-match ban for his head-high bump on North Melbourne’s Curtis Taylor.

Port Adelaide veteran Brad Ebert also faces a nervous wait after being reported for his head-high bump on GWS midfielder Harry Perryman on Sunday.

Ebert ran at full speed before collecting Perryman, but the damage wasn’t nearly as bad as to what Darcy suffered.

St Kilda’s Rowan Marshall was offered a $1000 fine for striking Nathan Wilson, while Adelaide midfielder Brad Crouch copped a $500 fine for misconduct against Eagles ruckman Nic Naitanui.
