"I'm absolutely delighted to be staying here," he said. "I'm a Cardiff boy, born and bred, and to be offered and sign a new deal is fantastic. I've only been with the seniors for three seasons and with all the young players such as Bradley Davies, Leigh Halfpenny and Tom James, we've got a very bright future."
Some strong displays in his debut season saw Warburton earn a place on the Welsh summer tour of North America in 2009., and he also came on as a replacement for the Blues during last season's historic Amlin Challenge Cup final victory over Toulon.
Selected as part of Warren Gatland's 2011 Six Nations squad, Warburton won his 11th cap in the win over Scotland. However, his focus is still on winning trophies with his region.
