South Sydney's premiership defence has been thrown into further chaos following a bizarre bottle-throwing incident which could see George Burgess suspended for two weeks.

Burgess launched a plastic drink bottle while sitting on the Rabbitohs interchange bench at rival Kane Evans as Evans walked from the field during the Roosters 30-0 win against the Rabbitohs on Friday night. The brain snap will cost Burgess two games even if he takes an early guilty plea. He will need to beat the charge to play against Cronulla in the Rabbitohs' elimination final as a grade-one charge – with his 20 per cent loading for a non-similar offence – will bring a one-game ban.

Burgess' actions came after Evans and Rabbitohs teammate Paul Carter clashed. Roosters player Sio Siua Taukeiaho was penalised for working Carter over as he tried to play the ball, to which Carter objected – throwing the ball in the direction of the Roosters players.
