Asamoah Gyan rocked Newcastle in the Wear-Tyne derby as he grabbed a dramatic point with a last-gasp goal.
The Magpies looked on course for victory after Kevin Nolan fired them into the lead early in the second half - until Gyan intervened.
Both teams missed early chances before Nolan netted when he turned home Shola Ameobi's knock-down.
And Newcastle looked like they'd hold out until Gyan took the roof of the Stadium of Light with his eighth goal of the season, and possibly the most important one he's netted thus far.
Manager Steve Bruce will doubtless be relieved to have taken a point as he stared a second derby defeat of the season in the face.
And his team kept going until the very end to grab a share of the spoils when Gyan knocked the loose ball home after Steve Harper had saved Phil Bardsley's shot.
It was a super ending for the red and white hordes who had created an electric atmosphere before the game by raising red and white cards to welcome the team on to the pitch.
In typical derby fashion the game begun at a frenetic pace with early chances at either end.
Newcastle threatened first; Joey Barton dinking a neat ball over the top only for Ameobi to slide the ball wide when through on goal with only three minutes gone.
But it wasn't long before Sunderland fashioned a response. Steed Malbranque played Darren Bent in, but the striker fired an angled drive at Harper's legs after doing well to slalom past Fabricio Coloccini.
Then Coloccini was in the thick of the action at the other end, firing a loose ball goalwards following a corner only to see his shot hacked off the line by Kieran Richardson.
It was breathless stuff as Sunderland responded by piling forward with the roar of the crowd reverberating in their ears.
A short corner routine produced a shooting chance for Malbranque 18 minutes in, but Harper was equal to the task and dived at the foot of his post to turn the ball behind.
And from the resulting set-piece the ball sat up perfectly for Ahmed Elmohamady 12 yards out, but a brave block from a Newcastle defender ensured the danger was averted.
The Black Cats were snapping into challenges as the pace was ramped up even more, and just before the half-hour Elmohamady got away from Coloccini and fired off a cross-shot which Harper did well to save down low.
The frenetic pace couldn't last forever, of course, and the game settled down somewhat with the break approaching although Ameobi should have done with a close-range header from a corner which he planted over the the top.
Bent came close to opening the scoring soon after the restart, but his attempted lob over an advancing Harper dropped wide of the post.
And Newcastle punished the miss as they stunned the Stadium of Light by taking the lead on 52 minutes.
A right-wing corner was knocked back across goal by Ameobi and there was Nolan to steer the ball past a helpless Gordon from point blank range.
Best was inches away from making it 2-0 as he narrowly missed a whipped ball across the box, while Gutierrez smashed a low drive wide as Newcastle looked to seal victory.
Gyan deflected a shot wide as Sunderland struggled, with Bruce introducing Bolo Zenden in an attempt to spark his side into life.
But the hosts just couldn't break down a stubborn Newcastle defence - until the final throw of the dice on a dramatic afternoon.
Piling forward late on, Jordan Henderson picked up a loose ball on the edge of the area and played in Bardsley, who fired a low shot across the box.
Harper saved well, but he could only look on in horror as the loose ball bounced against Gyan and looped high into the net.
Cue bedlam at the Stadium of Light as Sunderland grabbed a dramatic last-gasp derby point with virtually the last kick of the game.
