Sunderland will play Wycombe for a place in the English Championship.
The two clubs are through to the League One play-off final.
Wycombe had managed to get through over the weekend, while Sunderland managed a 1-1 draw in their second leg against Sheffield Wednesday to progress 2-1 on aggregate.
The game was a tense affair for both sides, with Wednesday eventually taking the lead in the 74th minute through Lee Gregory.
While Sunderland were made to sweat, they progressed thanks to a 93rd minute equaliser from Patrick Roberts.
A giant of English football, Sunderland will be hoping that promotion to the Championship, should they win the final against Wycombe, can be the start of their road back to the top flight.
