Ten-man Millwall secured a stunning upset with a last-minute winner to beat Premier League champions Leicester City and reach the quarter-finals of the FA Cup.
The League One side had defender Jake Cooper sent off in the 52nd minute for two bookable offences.
However, Shaun Cummings grabbed the dramatic winning goal when he collected Lee Gregory’s pass, cut in from the right side, went past a Leicester defender in the box and finished low past Ron-Robert Zieler.
Millwall, 33 places behind Leicester in the English football system, have reached the last eight of the competition for only the third time in 32 seasons.
Millwall were playing their fifth match of this year’s competition and had defeated Premier League sides Bournemouth and Watford in the last two rounds.
However, their chances of causing another surprise looked to have ended early in the second half when Cooper was dismissed.
He picked up his first booking at the end of the first half when he tried to kick the ball out of Leicester goalkeeper Zieler’s hands before he was sent off following a needless sliding challenge on Ahmed Musa, who was still in his own half and close to the right touchline.
Nevertheless, Neil Harris’ side, sixth in the third tier, were the better of the two sides for the remainder of the match with their manager making attacking changes as they pushed for the win.
And, in a dramatic conclusion, they got the goal and managed to hold on to spark jubilant scenes of celebration at a sold-out Den.
The Lions’ last appearance in the last eight came in 2012-13 and they will now be waiting to see who they get in the quarter-final draw.
That will take place at 18:30 GMT on Sunday and can be watched on the BBC News channel and the BBC Sport website, with commentary on BBC Radio 5 live.
Millwall will be joined in the draw by National League side Lincoln City after the Imps won 1-0 at Burnley to become the first non-league side in 103 years to make the FA Cup quarter-finals.
