Steven Naismith scored an injury-time header to seal an FA Cup third-round replay for Norwich as they twice pegged Southampton back at Carrow Road.
Maya Yoshida's own headed goal had appeared to be enough for Saints to advance after Virgil van Dijk's volleyed opener was cancelled out by Steven Whittaker's penalty.
But the Canaries refused to lie down and Naismith met Whittaker's cross unmarked to secure a dramatic 2-2 draw, with both sides now in the hat for Monday's fourth-round draw.
Plenty of Norwich fans steered clear of the game, with the usually bustling Carrow Road down to a sparse attendance of 12,479.
