Hosted by Darragh Maloney and broadcast live on RTÉ One at 9.30pm on Sunday, December 23, the live show will review what was a momentous year for Irish athletes and teams, and look back on the dramatic and memorable sporting moments of 2012.
Ronan O'Gara (2004) and Brian O'Driscoll (2009) were previous rugby winners of the national broadcaster's top sporting accolade. Golfer Rory McIlroy was the 2011 RTÉ Sports Person of the Year.
Leinster, having recaptured the Heineken Cup in May 2011, were last year's Team of the Year winners. There were four previous rugby wins in the Team of the Year category - Ireland in both 2004 and 2009, and Munster were honoured in 2006 and 2008.
Leinster head coach Joe Schmidt was also nominated for the Manager of the Year gong twelve months ago when Republic of Ireland soccer manager Giovanni Trapattoni was chosen as the inaugural winner.
The 2012 awards ceremony will again see the RTÉ/Irish Sports Council's Hall of Fame award presented to a very special Irish sporting legend.
