Kelly won the Hogan Cup with St Ronan's, Lurgan,[1] as well as representing Armagh at junior level before making his senior debut against Antrim in the 2021 Ulster Senior Football Championship, scoring a goal in that appearance.[2][3]
Kelly played in all of Armagh's league games in 2022, but was absent for much of the championship campaign owing to injury problems.[4] He returned for the All-Ireland quarter final against Galway, but in a fracas at the end of normal time, Kelly was judged to have gouged the eyes of Galway's Damien Comer, and received a 24-week ban.[5]
Kelly was part of the Armagh team which won the 2024 All-Ireland Senior Football Championship, scoring one point in the final.[6]
He plays club football for Clann Éireann, Lurgan, and was a member of their Armagh Senior Football Championship winning sides in 2021 and 2024.[7]
