Date of birth
Striker Mark Cullen joined United from Blackpool on a half-season loan deal during the January 2019 transfer window.
Northumberland-born Cullen signed for the Tangerines in the summer of 2015 and became a club favourite just one year later when he bagged a hat-trick against his former club Luton Town in the League Two play-off semi-finals.
It led to a memorable day out at Wembley when he scored the winner against Exeter City, which took Blackpool up to League One.
Cullen came through the youth ranks at Hull City and made 28 appearances for the Tigers, including four in the Premier League.
He had loan spells with Bradford City, Bury and Stockport County during his time with Hull. He played a big part in helping Luton Town return to the ranks of the Football League in 2015 before making his move up north.
