All Whites striker Chris Wood provided the assist for the match-winning goal that promoted his Leicester City side into the four-team Championship playoffs for the last Premier League promotion spot.
Tied 2-2 as 90 minutes ticked by, Wood laid on the pass for teammate Anthony Knockaert to score from close range in the first minute of added time, lifting Leicester to a 3-2 win over Nottingham Forest and over Bolton and Notts Forest for sixth in the Championship.
Bolton scored twice in first half stoppage time to level with Blackpool but could not find the goal that would put them into the playoffs, ending 2-2.
Leicester will face Watford in the two-leg playoff semifinals, after Watford missed a chance to earn automatic Premier League promotion with a 2-1 loss to Leeds United. Hull joined Championship winners Cardiff City in the Premier League for 2013-14 with a 2-2 draw against the Welsh club.
Brighton and Crystal Palace will meet in the other Championship playoff semifinal.
Earlier, Leicester fell behind Notts Forest in the third minute thanks to a goal from Simon Cox, before Matty James equalised for the Foxes in the 24 minute. Andy King gave Leicester a 2-1 halftime lead with a 43rd minute goal.
Leading at halftime, and with Bolton level with Blackpool, the playoffs spot was Leicester's to lose.
Elliott Ward equalised for Notts Forest in the 50th minute, and Wood had a close-range shot just miss to the left in the 57th minute, before his injured-time assist set up Knockaert's goal.
