Scotland stars Sean Lamont and Euan Murray will be playing top-flight rugby next season after Northampton secured a return to the English Premiership.
The Saints were relegated from the top tier last season but have made a remarkable job of regaining their status.
An 18-8 win over second-placed Exeter at Franklins Gardens meant they could not be caught at the top of National League One.
Jim Mallinder’s men have won 26 successive games this season and, combined with 20 bonus points, currently stand top of the table with an astonishing tally of 124.
Murray, now a fixture in the Scotland pack, came on as a replacement in the 54th minute to join former Scotland and Lions prop Tom Smith in Northampton’s front row.
Saints’ return to the Premiership is all the more impressive given the fact Lamont has not played this season after suffering a serious shoulder injury.
The Scotland winger expects to be fit in time for the start of next season, when he will be facing the likes of Leicester and Wasps once again.
