Carr became the youngest player to play at senior level for Donegal when he played at the age of 16 in 1978. He was a member of the Donegal under-21 team that won the 1982 All-Ireland Under-21 Football Championship.[1][3]
Carr spent time in Sligo and managed a Drumcliff-based association football team while there. He later returned to Letterkenny. He remained involved with his club after retiring from playing, and was subsequently appointed as its treasurer and coached its under-age teams.[1]
