Charlie Cameron is free to play against Essendon after being offered a reprimand for engaging in rough conduct against Port Adelaide defender Dan Houston.

Cameron was cited by the Match Review Panel for making late and high contact with Houston in the third quarter of Showdown XLII at Adelaide Oval on Saturday night.

The incident was assessed as careless conduct with low impact to the head, and classified as a $1,500 sanction.

Cameron has no applicable record which impacts the penalty, resulting in a $1,000 fine with an early plea.

Power ruckman Paddy Ryder has been offered a one-match ban for striking Crows forward Riley Knight.

The final-quarter incident was assessed as intentional conduct with low impact to the head, and classified as a two-match sanction.

Ryder, who has no applicable record which impacts the penalty, can accept a one-match sanction with an early plea.
