Manly have begun an audacious push for an exemption to play Tolu Koula in the NRL's round 14 after the centre suffered a head knock in the illegal tackle that defined State of Origin I.
Koula lay sprawled on the ground following a shoulder charge from Kalyn Ponga that led the Queensland fullback to be dramatically banished from the field in NSW's win.
NSW debutant Koula initially reported category-two symptoms before failing a head injury assessment in the sheds after leaving the field.
