A late Sofiane Boufal equaliser earned Southampton a 1-1 draw against Tottenham in the FA Cup on Saturday.
Son Heung-Min opened the scoring in the second half but Boufal's goal means that Spurs will host a replay for the second consecutive round.
Spurs had a glorious chance to take the lead in the opening 10 minutes but Son dragged his shot wide of the post.
Giovani Lo Celso thought he had scored the opener after 28 minutes but it was ruled out after the ball struck Son who was in an offside position.
The visitors grabbed a deserved goal just before the hour mark when Son drilled a strike into the bottom corner.
With two minutes remaining, Boufal blasted the ball into the top corner to deny Spurs the win.
Spurs host Manchester City in the Premier League next weekend while Southampton travel to league leaders Liverpool.
