Mason Munn, born on 30 March 2006 (age 20), is a Northern Irish goalkeeper on Rangers’ books, wearing squad number 54. At 6ft 3in (1.91m), he is a tall presence in goal, though his senior career so far is shaped far more by what he did away from Ibrox than by a squad listing there.
That spell came at Dunfermline Athletic in 2025-26, when he made eight league appearances. For a young goalkeeper, that was the meaningful stretch: proper senior minutes, a run of responsibility, and the part of his career that carries the most substance at this stage.
Munn remains a developing goalkeeper whose profile is still fairly narrow. Rangers hold his registration, but Dunfermline Athletic is the club most clearly attached to his senior record so far.
