The birth of rugby league coincided with a wave of Jewish immigration to Britain in the 1890s, and Jews in the big cities of northern England quickly took the game to their hearts. The same was true in Sydney, where a Jewish rugby league competition was played in the 1920s. This week's 'Rugby Reloaded' takes a look at the history of Jewish involvement in the sport, from pioneers like Eli Jacobson to superstars like Albert Rosenfeld, and modern-day administrators like Todd Greenberg and Simon Johnson.
