Video: Brian O'Driscoll nominates Tana Umaga in latest ice bucket challenge
Brian O'Driscoll renewed his rivalry with Tana Umaga this evening when he completed the ALS ice bucket challenge and immediately nominated the legendary All Black Tana Umaga.
The two men famously came face-to-face in the 2005 Lions Tour when O'Driscoll suffered a tour ending injury following a spear tackle from Umaga and Keven Mealamu.
The All Blacks went on to comprehensively win the series and the two players went on to become two of the greatest players Ireland and New Zealand has ever produced.
O'Driscoll is the latest high-profile figure to partake in the charity initiative and it remains to be seen how Umaga responds.
