Radwan and Blamire retained by England
The pair have been named in the 27-man group preparing for the 3pm kick-off at Rome’s Stadio Olimpico, which is being televised live in the UK on ITV.
Club-mate Callum Chick is also training with England during the week, with the Italian squad for the Six Nations including Newcastle lock Marco Fuser.
Fuser came on for the last half-hour of the Azzurri’s opening game, which saw them beaten 37-10 by France in Paris.
