Blackpool twice came from behind to defeat Nottingham Forest 4-3 at the City ground and progress to the Championship play-off final 6-4 on aggregate. Forest were unbeaten at home in 20 games and had not conceded at the City ground in more than 12 hours.
The hosts had the ideal start when Rob Earnshaw's early strike brought the two teams level on aggregate.
Blackpool were enjoying more of the play but Forest looked dangerous on the break.
In the 56th minute Blackpool went back in front through Campbell.
But as Forest pushed forward for a goal Blackpool clinically finished them off on the counter.
Campbell then scored in the 76th and 79th minutes for the first treble of his career.
Dele Adebola fired home a consolation for Forest in stoppage time but it is the Seasiders who are just 90 minutes from returning to the top flight of English football for the first time since 1971.
