Jamie Doyle is Bohemians’ first new signing ahead of the 2017 season.
The left-winger, who turned 23 yesterday, joins from Shelbourne having played in all four of UCD’s Europa League games in 2015.
Manager Keith Long said: “He’s a player who’s been on our radar for a while. He’s 6ft 3in, will offer an attacking threat and is capable of chipping in with a few goals.
“It’s a big step-up from the First Division but he has the ability to adapt to a higher level.”
