It came after Ellis dumped Atkins to the ground after he had been dispossessed of the footy, with the tackle likely to earn Match Review scrutiny in the coming week.

Last week's amendments to the Match Review's 'dangerous tackle' rulings won't come into effect in Ellis' case, as he didn't pin Atkins' arms in the tackle.

Instead, the Match Review will likely have to decipher whether Ellis' tackle consisted of more than one action or whether it was in one fluid motion.
