Wanderers have completed the signing of Cian Bolger from Leicester City for an undisclosed fee.
The 20-year-old central defender has signed a three-and-a-half year contract with the club.
Ireland-born Bolger progressed through the youth set-up at Leicester and has impressed in three separate loan spells with Bristol Rovers.
Dougie Freedman said: “Although he’ll train with the first team squad, Cian is one who will initially play in the development squad.
“We believe that he has the potential to be knocking on the door for a regular place in the senior team in the near future.”
