Josh Sargent scored an equaliser for Norwich that held Southampton to a frustrating 1-1 draw despite still stretching their unbeaten run to 18 games.
The hosts finally found the net after 70 minutes in a match with few chances at either end, when Kyle Walker-Peters broke down the right and left Adam Armstrong with a simple tap-in from a few yards out.
But Sargent brought the Canaries level eight minutes later on his first start since August, slotting the ball into the net from a Jonathan Rowe cross.
The draw leaves Southampton still three points behind Ipswich in third, while Norwich stay 13th.
