George named England Six Nations captain but Sinckler left out
George, who has 85 caps, is one of the few players absolutely assured of his place as England undergo a period of transition in the wake of regular captain Owen Farrell's decision to stand down from international rugby.
The uncapped players are Immanuel Feyi-Waboso (Exeter), Chandler Cunningham-South (Harlequins), Ethan Roots (Exeter Chiefs), Oscar Beard (Harlequins), Fraser Dingwall (Northampton Saints), Tom Roebuck (Sale Sharks) and Fin Smith (Northampton Saints).
There are recalls for Northampton's in-form back George Furbank, Bath scrumhalf Ben Spencer, whose last appearance was as a late replacement in the 2019 World Cup final, centre Henry Slade and hooker Luke Cowan-Dickie.
Prop Kyle Sinckler, reported to be on the brink of securing a move to French club Toulon, and number eight Billy Vunipola, are notable absentees.
"Building on the foundations of what the England team achieved in the Rugby World Cup, I have selected a squad that provides strong continuity and experience, whilst at the same time providing an opportunity to develop the talent of a number of new and less experienced players,” Borthwick said.
On George's appointment, he added: "Jamie has been a respected leader in this group for a number of years now. He is a quietly influential character who has an excellent tactical understanding and who sets high standards, whilst building strong relationships with the people around him.
"This, together with his previous experiences of captaining Saracens and the British & Irish Lions, leave him well-placed to lead the team."
The captaincy completes a remarkable journey for George who won his first 19 caps as a replacement behind former captain Dylan Hartley, but who was selected to start all three Lions tests in New Zealand in 2017 while an England understudy.
"I accepted with huge gratitude and enthusiasm," he said. "I love playing rugby for England. I hope that everyone has seen how much it means to me, I have never shied away from that. I am so excited about where this team can go and bringing the fans on that journey with us is something that I care about deeply.
"I don't underestimate the challenge ahead. Owen is a fantastic motivator and tactician, and we will undoubtedly miss his leadership. But I have got brilliant people around me, many of whom have won major tournaments, and utilising the great experience we have within the group is going to be crucial."
After their opening trip to Italy, England then host Wales, play Scotland in Edinburgh, host Ireland before finishing off away to France.
In the last three championships since winning the title in 2020, England have managed only two wins each season, finishing fourth, third and fifth.
