St Kilda will challenge the two-match suspension handed down to veteran ruckman Paddy Ryder when they head to the tribunal on Tuesday night.
Ryder's conduct was graded by the MRO as Careless, High Impact and High Contact, as he collided with young Hawks defender Will Day on Sunday afternoon.
Day was left concussed and did not return to the contest.
Saints COO Simon Lethlean stated the following on Tuesday: "We had until 11:00 am this morning to assess the MRO's original decision, and feel this is the best course of action to undertake."
The former Essendon and Port Adelaide ruck's case will be heard by the tribunal from 5:00pm AEST on Tuesday night.
As it stands, Ryder is set to miss this Saturday's clash with Gold Coast and next Friday night's battle with GWS.
MORE TO COME.
