The issue came to light after Magpie Isaac Quaynor sustained a severe 16-21cm gash on his right leg, following an attempted tackle on Wicks in the final term. The Swans stated post-match that Wicks' boots were standard-issue screw-ins, with a hybrid soleplate that includes plastic and aluminium stops.
"Following discussions with the AFL, it has become clear that these boots are not compliant with AFL regulations," the Swans said in a statement.
"The Sydney Swans will take steps to rectify this immediately to ensure that all boots are compliant going forward. The club has been in contact with Collingwood to express its regret for the incident and concern for Isaac, whom we wish a speedy recovery."
