Norm Smith Medallist Brian Lake faces double trouble when the AFL match review panel looks at the grand final.

The Hawthorn key defender Brian Lake collected Fremantle forward Michael Walters with an elbow to the head in Saturday's bruising clash.

There are double demerit points for grand final incidents and Lake is one of three players from the match who could have delayed starts to next season.

Teammate Cyril Rioli will also come under scrutiny for his "chicken wing" tackle on Dockers midfielder Michael Barlow.

Hawks legend Leigh Matthews has no doubt that Rioli is in trouble for the incident.
