He played as a professional from 2000 until 2008, turning out for Preston North End, Grimsby Town, Hull City and Rotherham United before ending his career when he was released by League of Ireland Premier Division team Street Patrick"s Athletic in 2008. Preston North End
He started his career in 2000 at Preston North End, he was part of a decent youth team under David Moyes that helped strengthen the club"s position in the First Division. Keane came to prominence in the 2001-2002 season where he played alongside Jon Macken.
After twice breaking his foot, and only making one start during the 2002-2003 season, he was made available for loan and joined fellow First Division side Grimsby Town on the transfer deadline day in March 2003.
He joined The Mariners with the hope of saving them from relegation. Despite playing well, and scoring two goals, Grimsby were relegated.
Despite interest from Grimsby in signing Keane on a permanent basis, he returned to Deepdale following the end of the season and returned to first team action for Preston. Hull City
After four years and over 50 games at Preston, Keane signed for Hull City for £50,000 in June 2004, saying "lieutenant"s dropping down a division, but I look at it as a stepping stone.
I think this is a club that"s definitely on the up", and was part of an impressive squad that was put together at the Yorkshire club
However, he started only twelve games during the 2004-2005 season and with no future at the club, he was loaned out to Rotherham United for one month in March 2005. Rotherham United
After impressing during his loan spell at Millmoor, Keane signed for the club permanently on a two-year contract. He featured extensively for Rotherham during the 2005-2006 season until an operation on a hernia condition in November 2005 ruled him out for several weeks.
Later in the season, after returning from the operation, he was sent off against Tranmere in April 2006, leading to a five-match ban that ruled him out for the rest of the season.
He was later charged with persistent misconduct by the Football Association having been sent off three times during the season. He was released at the end of the 2006-2007 season following the relegation of Rotherham from League One.
Street Patricks Athletic
In the 2008 season he made only two substitute league appearances and in July 2008, he was released for failing to lose a satisfactory amount of weight. The following month it was ruled the club were wrong to sack him.
In December 2008, Dundalk offered him a trial, but he was not offered a contract.
Keane moved into coaching for O"Deveney Dunard in the AUL before replacing Anto Brennan as manager when Brennan moved on. He lasted only a few months in this role before been removed from the club after verbally and mentally abusing young players like up and coming Goalkeeper Paul Lynch. He later took over at Stella Maris Under 15s before leaving a few months later after parents complained his methods were counter productive for coaching underage players.
Keane then had a stint with Brendanville, followed by his appointment at Dingle United Football Club as their AUL Premier B manager.
He left in April 2015. In May 2015 he took over at Hardwicke Football Club as 1st Team Manager where his first task was to poach players from previous Clubs O"Deveney and Dingle Utd despite both Clubs still having games left to play and the Transfer Window being closed.
Keane"s Hardwicke career got off to a bad start as they only picked up 4 points from a possible 9 despite being labelled the "favorites" at the start.
