Dylan Hartley and Courtney Lawes will be available for Northampton this weekend after being released from England duty.
Hartley and Lawes, along with team-mates Ben Foden and Lee Dickson, are among 10 players who have been released back to their clubs for Aviva Premiership action.
Wasps flanker James Haskell, Worcester's Matt Kvesic, Saracens pair David Strettle and Joel Tomkins, plus Bath prop David Wilson and Leicester back-row forward Thomas Waldrom have all been allowed to join up with their respective clubs.
Fly-half Owen Farrell, plus back-row forwards Ben Morgan and Billy Vunipola will continue their injury recoveries under a joint club-England medical programme at Pennyhill Park.
"This week is partly about recharging our batteries after a tough Test match," England coach Stuart Lancaster said. "But we trained well today and are in pretty good shape.
"Owen is still recovering from his tight quad muscle and probably won't train this week, but we are fortunate to have Toby Flood who came on and did well against France."
Lancaster's squad will reconvene at their Surrey base on Monday to continue preparations for the clash against Italy at Twickenham on March 10.
The unbeaten Six Nations Championship leaders then tackles Wales in Cardiff six days later in what could be a title decider.
