Northampton Saints secured a 49-41 victory over Castres in an Investec Champions Cup thriller, advancing to the quarter-finals for a third consecutive season. The home side overcame an early deficit after Castres scored twice through Ambadiang and Chabouni, taking a 12-0 lead before Northampton responded with a penalty try.

Castres received two yellow cards in the first half, reducing them to 13 men, yet they still maintained competitiveness. The game featured momentum swings throughout, with Northampton briefly taking control only for Castres to fight back through tries from Ardron and Karawalevu, keeping the outcome in doubt until Furbank's decisive try in the 56th minute.

England center Dingwall acknowledged the achievement, noting how special it is to consistently reach this stage. The victory caps off an impressive European campaign for Saints, who last season were runners-up. Their quarter-final spot was secured despite Castres' spirited performance and third yellow card in the 69th minute, which ultimately proved decisive in the high-scoring contest.
