Mark Johnson, Dustin Fletcher, Paul Barnard and Rob Forster-Knight will front the AFL tribunal tonight after being charged with engaging in a melee during the fourth quarter of last Saturday night's match against Brisbane. The Bomber players will be joined by Alastair Lynch, Tim Notting, Robert Copeland and Craig McRae who face similar charges. Johnson is the only player of the Essendon quartet to be previously charged with engaging in a melee.
