In the absence of their main Super Eagles star Awoniyi, Forest produced a truly 'Notting' performance.
Premier League club Nottingham Forest have been humiliated out of the Emirates FA Cup following a scandalous defeat in round three.
Forest suffered a devastating 4-1 defeat at relegation-threatened Championship side Blackpool on Saturday.
The Reds looked toothless offensively without their Super Eagles star Taiwo Awoniyi, who missed the cup game due to an injury.
Awoniyi missed the game due to a muscle problem as a remarkable second half display saw Blackpool book their place in the next round.
Relegation derby
The game at Bloomfield Road saw two relegation-threatened sides go head-to-head in the oldest competition in England, the FA Cup.
Blackpool find themselves in danger of dropping to League One from the Championship having failed to win any of their last nine matches heading into the game on Saturday.
Nottingham Forest find themselves in a similar situation but in the Premier League, where they are just two points away from danger.
The game presented both sides a chance to register a positive result that could potentially impact their seasons. But in the end, it was the Championship side who had the last better day and last laugh.

Marvin Ekpiteta opened the floodgates in the first half when he put Blackpool ahead at the break before Ian Poveda doubled their advantage after the hour mark.
CJ Hamilton made it 3-0 in the 71st minute, with Jerry Yates sealing the deal with a fourth goal three minutes from time.
Ryan Yates netted the final goal of the day in added time to reduce the deficit and make the result more respectable for the visitors.
