Ambrose Morgan The King of Redfern Souths d.1975 gunshot wound to the chest. Was 6 and a half feet and weighed 16 stone! Ambrose had only played a few third and reserve grade games over the years, but he was called up against the mighty Eastern Suburbs in an Amco Cup semi-final at Tamworth. Morgan came on with Souths trailing 2-9, and although Souths eventually lost the match, Morgan cut up the opposition scoring a try and setting up another for his good mate Donnelly. Fast and big, with a step and uncanny ball skills, the afro-haired smiling giant Morgan suddenly stood astride the league world like a colossus. Morgan was trumpeted as the new Beetson, high praise indeed after the match against Artie Beetson himself. Big Artie was then at his peak with Easts (stunning grand final winners over Saint George 36-0) and to give the dynamic prop this tag was a big call. Ambrose had the world at his feet, a chance to both make it in the big time and help his people as well, but no-one could have guessed what was to happen next. He only played 18 games.
