St Kilda young gun Anthony Caminiti is facing a nervous wait for the AFL match review officer's findings after an off-the-ball incident that left Collingwood's Nathan Murphy concussed.
Vision shows Murphy forcefully pushing Caminiti in the chest during the final quarter and the Saints forward responding with a raised forearm that felled his opponent.
Murphy, who later had words with the Saints contingent on the boundary line, will miss Collingwood's Anzac Day blockbuster against Essendon as a result of his concussion.
Caminiti landed at St Kilda during the supplemental selection period and has played a key role in a makeshift forward-line over the opening five rounds this season.
But the 19-year-old's impressive start is set to come to an end, with the incident likely to lead to Caminiti being sent to the tribunal, where the AFL would push for a ban of three matches or more.
GWS midfielder Tom Green is also set to learn his fate on Monday after a dangerous dump tackle on Hawthorn's Josh Ward.
Essendon captain Zach Merrett was handed a one-match ban for rough conduct over his similar dangerous tackle on Melbourne's Tom Sparrow.
Like Collingwood's Murphy, Bombers midfielder Merrett is also set to miss the traditional Anzac Day match.
