Report: Leeds starlet who once surprised Bielsa with his display close to sealing permanent transfer
The 20-year-old was a key part of the under-23 side that stormed to the Premier League 2 Division Two title this past season.
He also got the chance to make a couple of first-team appearances. However, it appears that the centre-back may move on before getting the opportunity to make his Premier League debut.
According to the Yorkshire Evening Post, Blackpool are close to signing Casey. It is noted that the youngster is open to the move as he looks for his chance in first-team football.
The report suggests that more of their starlets could follow suit, either permanently or on loan.

It may not surprise many Leeds fans that Casey could leave. He has been superb for the under-23s.
However, the Whites boast a fantastic amount of depth at the heart of their defence.
Marcelo Bielsa has Liam Cooper, Diego Llorente, Robin Koch and Pascal Struijk available to him. Luke Ayling can also feature in the middle.
Meanwhile, under-23 teammate Charlie Cresswell looks destined for a future first-team spot.
It is a shame. Bielsa suggested that he was surprised by how well Casey performed on his debut in the 2-0 win against Huddersfield in the Championship.
But a move looks to be best for all concerned.
Leeds will have their transfer kitty boosted as they look to improve their under-23 ranks following their promotion.
Blackpool meanwhile, will have landed an impressive youngster ahead of their return to the Championship.
And Casey can join a club where he is likely to be a key man.
