British & Irish Lions Test hooker Jamie George has signed a long-term contract extension with Saracens.
Saracens, the reigning European champions, said the England international's deal will keep him at Allianz Park until 2021.
George, 26, made his first-team debut for the club in 2009. He has won 17 England caps and started all three Tests for the Lions in New Zealand this summer.
"It's the club that I've grown up playing for, the club I've grown up supporting my whole life," George said.
"To be signing here for the long-term and to have played here for a long time already is a huge honour."
Saracens director of rugby Mark McCall added: "We're over the moon to secure Jamie's long-term future. He is fast becoming a world class player in his position, and is a key figure for both club and country."
