Sunderland are not done yet.
If there is one quality the Black Cats have shown in abundance this season, it is a kind of superhuman resilience.
They have demonstrated as much in individual games, across the campaign as a whole, and latterly in their absolute refusal to concede defeat in their quest for promotion to the Championship.
They have shrugged off the disappointing end to the League One season which put paid to their automatic promotion hopes, and instead seized their second chance via the play-offs.
Last night's goalless draw against Portsmouth in the play-off semi-final second leg on the South Coast was enough to earn them a place in League One's end-of-season showpiece final at Wembley.

It will be the Black Cats' second visit to the national stadium in the space of two months, following their EFL trophy final appearance at the end of March, and it means Jack Ross will become the first manager to take Sunderland to Wembley twice in one season.
Will it be a re-run of their classic 1998 First Division play-off final against Charlton Athletic? Or an all-new pairing against Doncaster Rovers?
That will be decided tonight when those teams play the second leg of their play-off semi-final at The Valley, with Charlton holding a 2-1 first leg advantage.
But Sunderland fulfilled their part of the bargain by silencing the Pompey chimes at Fratton Park.
Chris Maguire's stunning volley in the first leg at the Stadium of Light last weekend meant they held the whip hand, and ultimately that goal proved enough to win the tie.
At Fratton Park, goalkeeper Jon McLaughlin was called upon to make three fine saves to keep Pompey at bay, but there was never a feeling that Sunderland were under siege and clinging on by their fingernails.

In fact, Sunderland's game management - particularly in the second half - was excellent, with Ross getting his tactics spot on to nullify a potent Pompey attack that had scored 109 goals in all competitions this term.
This was the fifth meeting between the sides this season, with the two-legged play-off coming on the back of the two league meetings and the EFL Trophy final.
And that, along with the size of the stakes, meant there was always going to be an element of needle on the pitch.
But the ugliest incident of the night came not on the pitch but in the stands, when Sunderland's Luke O'Nien was nudged over the advertising hoardings and landed in amongst the Pompey fans, one of whom appeared to kick out at him.

It led to a flashpoint in which an incensed Lee Cattermole pointed out the fan to referee Peter Bankes, he spoke to the fourth official, and the supporter was removed by police minutes later.
O'Nien said after the game that the police had spoken to him but he had declined to press charges .
Ross, too, was keen not to let the Jack Ross reacts to Luke O'Nien's spat with a Portsmouth fan at Fratton Park overshadow the match.
He was already thinking about the final.
Sunderland's epic season will stretch to a 61st game, and this time it is winner takes all.
