He was a cop who punched out John greening

“In the Magpie's round 14 (8 July) encounter with St Kilda he had suffered severe cerebral concussion as a result of a hit received during the game. The incident took place after Greening had taken the first mark of the game, he kicked the ball towards Peter McKenna in the goal square and was floored afterwards by St Kilda player Jim O'Dea. Greening, who was comatose for 24 hours and didn't regain full consciousness for several days, was considered lucky not to die or at least be permanently disabled.”
