Not in recent times Browny, in the past he tried to get his feet under the grounding of the Ball, that was some time ago and the Laws were changed in Oz to address this issue.
He has never been a player to come in with knees to the back as a player grounds the ball, he had that a few years ago himself in a Test with a length of the field try with some no name trying to injure him as he was over the line. Almost caused a fight at the time.
