21-year-old D'Sena joins us from Pitching In Northern Premier League East Division side Bradford Park Avenue - a club the defender made 11 appearances for in the NPL Premier Division last season after signing in February 2024 from Chesterfield.
Commenting on the new signing, first-team manager Brad Munn said: "Firstly, I want to thank Chesterfield and Bradford Park Avenue for their help in getting Ryley over the line for us with such short notice.
"Ryley has been on the radar since entering the doors with chesterfield and we have played against him with our teams a couple of times.
"With recent events we needed to ideally get someone in that fit the mould or move forward with no one until we found that but just delighted Ryley himself wanted to be a part of us."
Munn added: "He should slot straight in to things here with his aggressive style and still being extremely comfortable in possession I believe he will be a real asset moving forward.
"Welcome to the club Ryley, excited to have you here."
