Collingwood's Levi Greenwood is set to come under scrutiny from the Match Review Panel, following an elbow to the jaw of Essendon's Zach Merrett in the third term of the Pies' clash with the Bombers on Saturday afternoon.

With the Dons leading by 33 points, Greenwood floored Merrett while attempting to apply a shepherd.

A scuffle broke out following the incident, with several Essendon players coming to their teammates' defence, as Merrett was forced to leave the field in the hands of the trainers.

Watch the incident in the video above.
