Cardiff Blues Director of Rugby, David Young said,
"Gethin has obviously proved this year that he is the number one prop in Britain and is the cornerstone of the Blues scrum. We are keen to build a pack around him and it is a testament to the ambition of the region that we want to hold on to players of Gethin's calibre.
"With quality players such as Rhys Thomas and Rhys Williams also extending their contracts with the Blues and wanting to stay here it is encouraging to see that the players share the coaches belief that we are heading in the right direction".
Jenkins who played in all three of the Lions tests in New Zealand this summer joined the Cardiff Blues in 2003. "Obviously I'm happy to have signed the contract and commit myself to the Cardiff Blues. There is a great feeling amongst the squad and we are all keen to develop our careers here. To have a prop of Dai's quality coaching you is obviously of huge benefit to a front row forward such as myself." Gethin Jenkins said.
