The AFL will alter the interpretation of the studs-up rule with immediate effect.
It comes after Richmond forward Jack Riewoldt was penalised twice for placing his studs into an opponent’s back while completing a mark in Sunday’s win over West Coast.
Collingwood defender Jeremy Howe was also pinged for a similar action in the Queen’s Birthday clash earlier this season.
Tigers coach Damien Hardwick called for “common sense” over the studs-up rule and questioned why it was introduced in the first place.
“The studs up rule was brought in to ensure players did not employ their studs in marking contests in a manner likely to cause injury,” AFL operations boss Steve Hocking said in a statement.
“Although the two incidents from the Richmond v West Coast Eagles match were adjudicated according to the current interpretation, the AFL acknowledges there is a need to adjust the interpretation of rough conduct free kicks relating to the use of studs in marking contests and will make this change effective immediately.”
The rule was introduced late last year following the fly-kick marking technique used by GWS star Toby Greene.
