THE AFL is weighing up an appeal against the two-week suspension to Richmond's Bachar Houli handed down by the AFL Tribunal on Tuesday night.

Houli's backhand hit on Carlton's Jed Lamb, which left the Blues forward knocked out and unable to play on, was referred directly to the Tribunal by the Match Review Panel.

In banning Houli for two matches, the Tribunal took into account character references from Prime Minister Malcolm Turnbull and media personality and academic Waleed Aly.

An AFL spokesman said football operations manager Simon Lethlean would make a call on any appeal against the lenience of the decision, and could gather advice throughout the morning.

To successfully appeal Houli's ban, the AFL would have to establish the decision was so unreasonable that no Tribunal acting reasonably could have reached that decision having regard to the evidence.

An appeal would have to be lodged by midday on Wednesday.

It would be heard by three members of the Appeals Board, which consists of Peter O'Callaghan (chairman), Brian Collis QC (deputy chairman), Brian Bourke, Michael Green, Stephen Jurica and John Schultz.
