Wilson. Cavan football from the 1930s through to the 1950s relied heavily on Mullahoran and Cornafean players.
The parish also has a separate hurling team known as Mullahoran St Joseph's, who are the current Cavan Senior Hurling Champions for 2016. The club had been unbeaten in the Cavan Senior Hurling Championship since 1990 until surrendering the title to Ballymachugh in 2011. The club's run of 21 consecutive Championship titles is a record in the GAA. The club also appeared in the Division 3 Ulster Senior Hurling League in 2006, but lost to Bredagh from County Down.
