Australia's Andrew Symonds could face disciplinary action after flattening a streaker during Tuesday's one-day international against India.
Symonds was standing at the non-striker's end during Australia's innings when the man evaded security and ran onto the Brisbane pitch.
The all-rounder then floored the invader with a shoulder charge.
The players' code of conduct forbids physical assault of a rival player, official or spectator.
The sanction for that is a suspension, ranging from five Tests or 10 one-day internationals, up to a life ban.
The streaker, who was escorted from the Gabba field by police, faces a fine of up to £1,400 for the pitch invasion and is expected to be charged with wilful exposure by Queensland state police.
