The new arrival from Crystal Palace has been allocated no.31, the slot previously occupied by former loan signing Martin Dubravka, who was recalled by parent club Newcastle United recently.
The announcement of Butland's move comes with the Reds set to face Everton in the third round of the Emirates FA Cup this evening (Friday 6 January). Jack will be ineligible to play in this fixture, but will be eager to see United earn a fifth consecutive victory in all competitions since the season’s restart.
The 29-year-old wore the no.1 shirt at Palace and Stoke City, and was close to his current jersey's number when wearing 30 for Leeds United in 2013/14.
