Ballinderry defended the Derry Championship in 2002, but lost in the semi-final stage of the Ulster Club Championship to Errigal Ciarán. Muldoon won the Ulster Tennent's Monthly Merit Award for October 2002 for his performance against Mayobridge in the Ulster Club quarter-final. His performance in that game was described as a "masterful display", scoring vital points and was the "defensive anchor in a tense final quarter". Muldoon also helped New York club Westmeath reach the semi-final of the New York Senior Football Championship in 2002, but they were defeated by the Kerry club.
