The match had proven to be somewhat of a stalemate up until a flash point in the 79th minute, which resulted in Jose Fonte being shown a red card for a last-man challenge on Fabio Borini.
The Black Cats capitalised on the one-man advantage less than six minutes later, with Jermaine Defoe finding the back of the net following neat build-up play from Lamine Kone.
Southampton will see the draw against a struggling Sunderland team as two points dropped, especially as it was a golden opportunity to continue their push for a place in the Europa League next season.
Despite undoubtedly being upset at conceding so late in the contest, the point the Black Cats picked up could prove to be invaluable in their push to avoid relegation this season as it takes them out of the drop zone with just nine matches remaining.
Very disappointed not to bring home 3 points today. The support was amazing though as it always is! Thank you!!! #safc@SunderlandAFC

Following the 0-1 we did great, considering we were 10 against 11. Prior to this, not at our level. pic.twitter.com/FZOv2Fs3ea

Good attitude from the team to level the game with 10 men. That's the way. We'll give everything in the next one! pic.twitter.com/hcOSTWmvHe

"For 85 minutes, we were not at the level I expect of Southampton. I think we lack confidence at the moment. They made it very difficult with their defensive organisation. We played better football with one player less on the pitch."
"The dejection amongst us all is clear. It was so important to see this game out. We know how important three points would have been. If we'd have got the win, we'd have had a gap for next weekend when we're not playing. We dropped a massive clanger in those last few seconds.

23 - Jermain Defoe has scored more Premier League goals as a substitute than any other player in the history of the competition. Super.
