Career
He first came on the Kerry senior scene in 2002 under the management of Páidí Ó Sé. However Scanlon failed to establish himself as a regular until 2007 due to serious competition from William Kirby, Eoin Brosnan and Tommy Griffin. Since then he has started regularly in centre half back, winning the Munster Senior Football Championship and All-Ireland Senior Football Championship with Kerry.
In recognition of his efforts during the 2009 championship, he was awarded with an All-Star.
Scanlon is now the senior defensive figure for Kerry since the retirement of the legendary Darragh Ó Sé in early 2010.
