SPAL secured a dramatic promotion to Serie A after 49 years out of the Italian top-flight despite falling to a 2-1 defeat at Ternana on Saturday.
Forward Mirco Antenucci had given SPAL an early lead with his 18th league goal of the season, only for Ternana to hit back thanks to a double from Stefano Pettinari before half-time.
With promotion rivals Frosinone drawing their game going into the closing stages it looked as though SPAL's promotion party would be delayed, until Fabio Ceravolo struck deep in injury-time to give Benevento a 2-1 win in that match.
SPAL played in the third-tier Lega Pro last season and have now secured back-to-back promotions to reach Serie A under head coach Leonardo Semplici, with the club set to face off against giants including Juventus, AC Milan and Inter next season.
