Graham in England squad
The squad will fly out to Portugal to prepare ahead of the match in Rome on Sunday February 4.
Graham, who joined the Falcons last summer from Jersey, is yet to be capped at full international but has impressed for the Falcons during his half-season with the club.
Falcons director of rugby Dean Richards said: “It’s great news for Gary that he has been retained in the England squad after training with them a couple of weeks ago down in Brighton.
“Hopefully he will get some minutes on the field during the Six Nations and we will begin to see more of our players called up by the England management in future.”
The Falcons already have three players in the Scotland squad for the 6 Nations, having seen call-ups for hooker Scott Lawson, prop Jon Welsh and centre Chris Harris.
