Saints have been handed a welcome boost ahead of Friday's big game at Bath with the news that Teimana Harrison has been released by England.
Harrison was an unused replacement in last Saturday's Six Nations win against France at Twickenham, but will not be involved against Wales in Cardiff on Saturday evening.
That means last season's players' and supporters' player of the year could play a part for Saints at The Rec on Friday night.
Jim Mallinder's men are just five points behind fourth-placed Bath in the Aviva Premiership table, knowing a win this week would be crucial to their hopes of finishing in the top four.
And Harrison's presence would strengthen a back row already shorn of Tom Wood and Louis Picamoles.
Picamoles is with France and Wood remains in the England camp for the clash with Wales, with Dylan Hartley and Courtney Lawes also retained by England boss Eddie Jones.
Bath duo George Ford and Jonathan Joseph also remain part of the England squad for Saturday's game and will play no part against Saints.
England's 24-man squad: Forwards: Jack Clifford (Harlequins), Dan Cole (Leicester Tigers), Jamie George (Saracens), Dylan Hartley (Saints), James Haskell (Wasps), Nathan Hughes (Wasps), Maro Itoje (Saracens), Joe Launchbury (Wasps), Courtney Lawes (Saints), Joe Marler (Harlequins), Matt Mullan (Wasps), Kyle Sinckler (Harlequins), Tom Wood (Saints); Backs: Mike Brown (Harlequins), Danny Care (Harlequins), Elliot Daly (Wasps), Owen Farrell (Saracens), George Ford (Bath Rugby), Jonathan Joseph (Bath Rugby), Jonny May (Gloucester Rugby), Jack Nowell (Exeter Chiefs), Henry Slade (Exeter Chiefs), Ben Te’o (Worcester Warriors), Ben Youngs (Leicester Tigers)
