Byrne is due to join on an emergency loan deal, which can keep him at Glanford Park for a maximum of 93 days.
The move comes after United have received bad news regarding the groin injury Christian Ribeiro picked up at Northampton, with the player likely to be out for a number of months.

Massive admiration for Cliff Byrne but really can't see how he will improve the squad. Big personality in the dressing room though

Head over heart. Football over personality and his past history. Is Byrne a good acquisition for this Iron side?
