Radlinski, 33, ended his career three years ago, and returned to the game earlier this year as Wigan’s scholarship coach.
“Kris will bring a wealth of experience to the playing squad,” said Smith. “He is an excellent role model for the players and I’m sure will be a welcome addition.”
Radlinski fills the gap left by Steve McNamara, who will not travel to Paris due to his commitments with Bradford.
Smith added: “The aim of involving Kris in the squad for the French trip is for him to take a look at us and for us to take a look at him with a view to a potential role in this autumn’s Four Nations.
Radlinski, who represented England on 10 occasions and won 20 Great Britain caps, said: “I’m really looking forward to being part of the England set-up again in what is an important year for the national side following last year’s World Cup.
“In Paris I hope to be involved in some of the coaching whilst learning from Tony. I’ll also be calling on my previous experience in the international side to give advice to some of the younger players in the squad.”
