Howard has made five appearances for Warriors this season and has racked-up an impressive four tries, including a brace against Bizkaia Gernika on his first start for the club.
There are two changes in the 32 as Harlequins centre Harry Sloan and Leicester Tigers wing Henry Purdy come into the squad.
Hunter said: "We've made a couple of changes to the squad and brought in two guys who have been performing consistently well at their club. Both Harry and Henry are talented players and we're excited to see what they can bring.
"Our focus at the moment is solely on our own preparation and that first Six Nations game against Scotland in Plymouth.
"They've had a warm up game and they'll be coming at us from the first whistle, but we've trained well and we're looking forward to getting out there on February 1."
England will face France in their third game of the competition in a clash which is set to be held at Sixways.
