Miller later 'Went North', joining professional rugby league team Hull FC (Heritage No.98).

He was chosen for the final game of the 1896 Home Nations Championship, against Ireland; one of only two new caps to be brought into the Welsh team along with Llewellyn Lloyd.

Miller found himself out of favour with the Welsh selectors until he was recalled four years later for the 1900 Championship replacing Llanelli's David Daniel.

This was the beginning of the First Golden Age of Welsh rugby, and Miller was part of the team that won all three of the 1900 Championship games to lift the Triple Crown.

Wales won the opener against England and the final game to Ireland, but were outclassed against Scotland at Inverleith.
