The Bears have not lost on home soil since March, but Northampton have won their last five matches against Bristol in all competitions dating back to November 2008 and will look to keep that record intact this weekend.
Director of rugby Chris Boyd makes two changes to his starting XV after the narrowest of defeats in Bath last weekend, bringing centre Luther Burrell back into the midfield to join Piers Francis and Ehren Painter into the front row alongside co-captains Alex Waller and Dylan Hartley.
Saints back three of Tom Collins, Taqele Naiyaravoro, and Ahsee Tuala continue together, while Cobus Reinach and Dan Biggar make their fifth straight starts in the half-back positions.
Saints engine room will not be short of height with towering locks David Ribbans and Courtney Lawes continuing, while Teimana Harrison keeps hold of the No.8 jersey with Jamie Gibson and Lewis Ludlam either side of him after both flankers impressed in torrential conditions at Bath.
Amongst the replacements, Andrew Kellaway is named again after making his Saints debut last weekend, with the likes of Harry Mallinder, Mitch Eadie, Alex Mitchell and Api Ratuniyarawa all also looking to make an impact off the bench.
“[Bristol] are different from most Premiership teams,” Boyd commented. “They’re very optimistic, they’re happy to play in deep territory, they’re happy to play behind the gain line and that means you’ve got to be really vigilant.
“They’re also very aggressive defensively so they pose not a normal Premiership challenge but something different. And I think what they’re doing, they’re doing pretty well.
“We’ve talked about the fact that we need to just keep concentrating on our own performance, find a bit of steel from somewhere, and get what we want to do right.”
