BEN CUNNINGTON is set to come under the scrutiny of Match Review Officer Michael Christian after an errant elbow to the face of Port Adelaide's Brad Ebert.             

The North Melbourne star backed into Ebert in the third term after disposing of the ball and struck him flush on the chin.

Ebert went straight to the bench after the incident and appeared groggy, but returned to the field shortly afterwards and kicked a goal. 

Cunnington has already faced MRO scrutiny this season, escaping with just a fine for an off-the-ball gut punch on Fremantle's Nathan Wilson in round one.
