George signs contract extension at Allianz Park
The 25-year-old has signed a new multi-year contract with the Premiership champions, the club with whom he joined in 2008.
Having initially dovetailed with Springbok hooker Schalk Brits as Saracens' regular No.2, George has become a key squad member since his graduation from the Saracens Academy.
George, who has made 136 Saracens appearances, started in the 2015 Premiership Final before being called up for England's 2015 World Cup squad after a superb individual season for the north Londoners.
"I've loved every second I've spent at the club over these last six seasons, so I'm delighted to have extended my stay here," George said.
"I really buy into what we are doing here at the club. Saracens have looked after me so well and I'm playing alongside my best mates, which means a huge amount to me.
"It's such a special environment, and if you couple that with the brilliant coaching staff that we have here, you constantly feel like you are developing as a player and as a person every single day. I'm looking forward to being able to carry on with this incredible journey at Saracens."
Speaking about securing George's services, Saracens Director of Rugby Mark McCall said: "One of the big positives over the last few seasons has been the emergence of a lot of our young talent that has been grown in-house, and Jamie has been at the forefront of that.
"We are delighted that he has committed his long-term future with the club and we are all very excited to see Jamie continue to excel for both club and country over the next few years.
"Jamie served a long apprenticeship coming through the ranks, and his patience is beginning to bear fruit judging by his performances over the last 18 months. It's great news that he is the latest player to commit his future to the club."
