Frank Heaney was one of a clutch of Irishmen to sign for Leeds City in the summer of 1911. He was accompanied to Elland Road by his brother John, both men previously playing for St James' Gate in Ireland.

John never made the City first team, but Frank had a couple of appearances in 1911/12. His debut came in a 5-0 defeat against Wolves at Molineux on 16 December. Heaney gave away the third goal when he brought down Parsonage to concede a penalty. He was described as "hesitating, and altogether too slow to cope with the sprightly Wolverhampton forwards".

Frank appeared once more, on 30 March against Derby at Elland Road, when Leeds lost 1-0.

Both brothers left City during the summer after the appointment of Herbert Chapman as manager and they never played professionally again.
