|European Rugby Challenge Cup|
|Venue: Franklin’s Gardens Date: Saturday, 8 December Kick-off: 15:00 GMT|
Director of Rugby Chris Boyd has given a number of Saints youngsters another opportunity to impress.
Dragons head coach Bernard Jackman has himself made eight changes for the trip to Franklin’s Gardens.
Centre Jack Dixon and prop Lloyd Fairbrother will make their 100th appearance for the region.
Biggar partners scrum-half Alex Mitchell for Saints, who makes his first start in four matches and Taqele Naiyaravoro remain on the wing.
Luther Burrell starts at 12 with Rory Hutchinson at outside centre for the first time this season after recovering from a knee injury.
Academy players Ollie Sleightholme and George Furbank make their European debuts and complete the back three.
Prop Alex Waller captains the side with James Fish coming in at hooker and Ben Franks also starting in the front row.
Api Ratuniyarawa and Alex Moon start and Tom Wood is recalled at openside flanker to join Jamie Gibson and Teimana Harrison at the base of the scrum.
Will Davis and Fraser Strachan are in line for European debuts if they come off the bench.
For the Dragons, Dixon returns in the centre alongside Adam Warren with Dafydd Howells and Zane Kirchner on the wings and Hallam Amos moving to full-back.
Tavis Knoyle starts at scrum-half with Josh LeWIS at fly-half in place of Arwel Robson, who has a hamstring problem.
Samoa international lock Brandon Nansen and back row Nic Cudd return to the pack.
Dragons are second in Pool 1 with Northampton Saints third.
Saints will be looking to complete the double over Dragons in this season’s competition after their 35-21 win at Rodney Parade in October.
Dragons are hoping to “restore pride” after last weekend’s heavy Pro14 home defeat by Leinster.
“It will be an incredible tough game as Northampton Saints have lots of quality,” Jackman said.
“However, we want to bounce back from last week’s disappointing display and it’s an opportunity to show the character in the squad.”
