He's here to be involved in the first-team says Mick as winger pens deal until 2016
The 19-year-old wideman is expected to appear for the U21s against Millwall on Monday, with the paperwork over his move from Ireland now complete.
“I’m delighted we have Dylan with us now,” said Town boss Mick McCarthy.
“He’s blistering quick, plays on the right and he’s got a fair bit of ability. He’s got a goal in him as well.
“He’s being playing as well and he’s here with a view to being in the first-team. He will play in the U21s next week if everything is okay and we will go from there.”
