Richmond’s Bachar Houli has been referred directly to the AFL tribunal over his off-the-ball hit on Carlton’s Jed Lamb.

The veteran Tiger knocked Lamb unconscious with a swinging round-arm blow in the first quarter of Sunday’s clash at the MCG and is unable to enter an early guilty plea.

In a surprise move, West Coast defender Will Schofield was offered a one-match ban for striking Melbourne’s Clayton Oliver – who was roundly criticised for making too much of the contact – while North Melbourne’s Ben Cunnington was offered a one-game suspension for striking the Western Bulldogs’ Toby McLean.
