Jason Demetriou has urged the NRL to impose harsher suspensions for cannonball tackles after Liam Knight suffered a season-ending ACL injury from what the South Sydney coach said was a "deliberate" act of foul play in the NSW Cup.
Knight would have returned to the first grade side against Newcastle this Friday had he not been targeted by Parramatta's Solomone Naiduki in a cannonball tackle - an illegal move where a player's legs are taken out from behind as he is being held upright by another defender.
