Richmond ruckman Toby Nankervis has been charged with striking Adelaide wingman David Mackay.

Mackay came from the ground for assessment after being struck in the face with an errant arm from Nankervis in the third quarter at Adelaide Oval on Sunday night.

Based on the available evidence, the incident was assessed as careless conduct with medium impact to the head.

The incident was classified as a two-match sanction, but because Nankervis has no applicable record which impacts the penalty he can accept a one-game ban with an early plea.
