Judson won his first international cap when, as a member of the first class team Llanelli, he was selected to play in the inaugural Home Nations Championship against England.
Under the captaincy of Charles Lewis, Judson was one of three Llanelli players in the Wales squad, the others being Alfred Cattell and Harry Bowen.
Wales was competent, but unspectacular, and was out-classed by the Australian wing Charles Wade in a four tries and two goals to nil loss.
Judson was reselected for his second and final international game, against Scotland, as part of the same Championship.
Wales lost by three goals to one, but Judson scored the Welsh try, making him the first ever try scorer against Scotland for his country.
