Ashley Williams and Everton could both be sanctioned by UEFA after a melee instigated by the Welshman saw a fan holding a child appear to aim a punch at a Lyon player.
Toffees skipper Williams' shove on OL goalkeeper Anthony Lopes after the hour mark sparked heated confrontations between several Everton and Lyon players in front of the Howard Kendall Gwladys Street End.
As they moved to the advertising hoardings, a supporter holding a child in one arm appeared to push Lopes in the head and seemed to aim a punch in the direction of the keeper.
