The "journeyman" started his career with
Blackburn Rovers spending 3 years at the club. He returned home to sign for his home town club
Bray Wanderers in time for the 2001/02 season making his
League of Ireland debut as a substitute at
Tolka Park on 9 November. He made a handful of appearances at the club when
Paul Doolin offered him regular first team football at
UCD and so Doyle was on his way again. He scored on his debut for
UCD on the first day of the 2002/03 season against
Bohemians and his performances that season impressed
Stephen Kenny enough to offer him a move to Bohemians at the end of the season. Doyle made a decent start to life at
Dalymount and played in all of Bohs' four
2003–04 UEFA Champions League qualifiers but he fell out with Kenny and in mid-2004, he returned once again to
St Patrick's Athletic. He has since played for
Bray Wanderers (again) and
Macclesfield Town. On 4 July 2007, Doyle agreed to sign for
Dundalk from
Macclesfield Town. He was released at the end of the 2007 season by Dundalk and signed for Sporting Fingal F.C. at the start of the 2008 season and ended the season as First Division top scorer. Fingal achieved promotion to the Premier Division in 2009 and better was to come as Fingal and Doyle won the
FAI Cup when beating
Sligo Rovers 2–1 at
Tallaght Stadium. On 4 March 2010 he re-signed for Bray Wanderers. In his three spells at his hometown club Doyle scored 5 goals in 59 total appearances. ==International career==
