A new arrival from Woking at the start of June, Josh went on to make 20 appearances for Boro in all competitions this season.
Along the way, Casey captained the team to eight wins and five clean sheets in The Vanarama National League South.
We would like to thank Josh for his contributions during his time at the Club and wish him all the best for the future.
Manager Spencer Day commented: “I’m genuinely sorry it didn’t work out with Josh.
“Another club will get a fantastic young man and I wish him nothing but success for the future.”
