The Northampton Saints starting line-up for Friday's Challenge Cup semi-final against Harlequins shows four changes.
Two of the changes are in the back line, with the remaining two both coming in the forwards.
Out wide James Wilson comes in at full-back, with England Under-20 centre Tom Stephenson wearing the number 12 shirt.
Up front James Craig pairs with Samu Manoa in the second row, with Calum Clark - who made his 100th appearance against the Exiles - coming off the bench to start in the back row.
The Saints coaches have also named a strong bench, featuring the likes of Courtney Lawes, Tom Wood and Luther Burrell. Mike Haywood returns to the matchday 23 after missing last Sunday's win.
Meanwhile, there are three changes for Harlequins to the side which beat Leicester Tigers last week as Charlie Walker returns from an injury sustained against Clermont Auvergne in January to start on the right wing.
Ben Botica starts at fly-half replacing Nick Evans who picked up a knock during last week's match.
In the forwards, Joe Marler returns to loosehead prop in place of Mark Lambert, as the second and back-rows remain unchanged.
Among the replacements, Louis Grimoldby will look to make his first European appearance for the club.
