Northampton welcome back England duo Dylan Hartley and Courtney Lawes for their Aviva Premiership clash with London Irish on Saturday.
Hartley and Lawes both started in England's RBS Six Nations victory over France last weekend but have been released back to the Saints to take part in club action.
Full-back ben Foden and scrum half Lee Dickson retain their places following the 25-23 victory over Bath after they were also given the green light from England.
That allows director of rugby Jim Mallinder to name an unchanged back-line as Northampton attempt to boost their hopes of a top-four place.
Hartley and Lawes come into the pack at hooker and lock respectively, while Samu Manoa moves into the back row to replace Ben Nutley.
London Irish make just one change for the contest, with Jon Fisher coming in at No 8 to replace Chris Hala'ufia, who has been banned for two weeks.
The Exiles will be hoping to gain some much-needed momentum after securing a 30-19 victory over Wasps last time out.
