The defender conceded to coach Chris Scott he made an error.

Cats star Jeremy Cameron and Richmond's Marlion Pickett can accept $1,000 sanctions for wrestling.

Meanwhile, St Kilda's Zak Jones escaped punishment for his bump on Luke Parker in the Saints' 51-point loss to Sydney, with his actions deemed "not unreasonable in the circumstances".

The MRO found Jones was "in a near stationary position and turns to brace for contact".
