Burgeoning Northampton half-backs James Grayson and Alex Mitchell will mark a half-century of appearances for Saints when they feature against Harlequins this weekend.
Fly-half Grayson, 22, has already notched up over 300 points in his fledgling career in Black, Green and Gold, while 23-year-old half-back partner Mitchell has an impressive 15 tries to his name for Northampton – and both have been named as starters by Chris Boyd.
Saints are unbeaten on home soil against Harlequins since 2012, offering a good chance to rebound from their 32-23 defeat to Sale Sharks last weekend in the opening round of the new Premiership season.
The hosts welcome Lewis Ludlam back into the 23 for the first time this season from international duty, with the flanker starting in the back row and skippering Northampton alongside loosehead prop Alex Waller in his new role as Club co-captain.
Reece Marshall makes his first Saints start since May 2019 at hooker, with Paul Hill extending his run at tighthead to complete the front row.
David Ribbans, who returned from England camp last week to come off the bench for Northampton, is selected to start against Quins alongside Fiji international Api Ratuniyarawa in the engine room – meaning Nick Isiekwe shifts into the back row alongside Ludlam and Tom Wood, who slots in at No.8 with Teimana Harrison out injured.
Tom Collins kicked off the new season with a try last time out against Sale, and the 26-year-old flyer continues in the back three; Ahsee Tuala also continues on the opposite wing, but Harry Mallinder comes into the Northampton XV at fullback for his first start since March after impressing on his return from injury last week.
As for Harlequins, who suffered a 33-3 defeat to Exeter last Friday, Paul Gustard has not been triggered into making a knee-jerk reaction to the heavy defeat, making only one change.
Matt Symons left the curtain-raising match earlier through injury and has been replaced in the second row by Glen Young.
England centre Joe Marchant and Scotland scrum-half Scott Steele make their return to the matchday-23 on the bench, after being released by their respective national sides.
Positive signs for James Chisholm in his recovery from a knee injury allow the back row to take a place among the replacements, where 20-year-old lock Hugh Tizard will also sit ahead of a prospective debut.
Head of rugby Gustard said: “Whilst we were disappointed to lose in the fashion that we did against Exeter last Friday, as a squad and as a support staff we felt for 71 minutes we were competitive against Europe's finest.
“We now move on and will have to up our game against a very well-coached and talented Northampton Saints team.
“We're pleased to welcome back three of our international representatives in Scott Steele, James Lang and Joe Marchant, who will add real quality to our matchday 23. We look forward to playing a full, disciplined 80-minute performance on Saturday.”
