Manchester United Healy was born and raised in Killyleagh, Northern Ireland, and played for Crossgar,
Lisburn Youth and Down Academy High School in
Downpatrick. He made his
Premier League debut on 23 December 2000 in a 2–0 victory against
Ipswich Town at
Old Trafford; he came on as substitute in the 60th minute, and with 10 minutes remaining, he hit the post denying him a debut goal. This was his final appearance for United as he signed for
First Division club
Preston North End six days later, initially on loan to allow him to play against Sheffield United on 30 December; Healy scored the opening goal as Preston took a 2–0 lead, only to end up losing 3–2. A permanent move was completed on 3 January 2001, as Preston paid Manchester United a fee of
£1.5 million, before Healy signed a four-and-a-half-year
contract.
Preston North End Healy made his debut for Preston against
Sheffield United on 30 December 2000; he scored after just four minutes in the 3−2 loss at
Bramall Lane. By the end of January 2003 he had made only 23 league appearances but scored five goals. Healy joined
Nigel Worthington's
Norwich City on a month's loan at the end of January. In the end, he stayed for the remainder of the season. However, in 13 appearances for the "Canaries" he scored only scored past
Sheffield Wednesday and
Wimbledon. Having attempted to sign him from Man United two years previously, Norwich attempted to sign Healy permanently from Preston but were denied by Brown. During his time at
Elland Road he was linked with dozens of moves to other clubs, the most notable rumour reported in the press being a potential £3 million move to
Manchester City. He scored his first goal for Fulham in a pre-season
friendly against
South China in the
Asia Trophy, with a low diving
header. He scored fifty seconds into his league debut for the club following a mistake from
Arsenal keeper
Jens Lehmann. He also found the net in his second game against
Bolton Wanderers, in a 2–1 win at
Craven Cottage. However, he only scored two further top-flight goals in the season (past
Reading and Sunderland), as well as two cup goals past Bolton and
Bristol Rovers. Following the sacking of Sanchez, new
manager Roy Hodgson preferred a
strike partnership of the American pairing of
Brian McBride and
Eddie Johnson, leaving Healy on the bench. In July 2008, Healy caused controversy when he adopted the posture of a flute player (similar to a previous incident involving
Paul Gascoigne) in response to a question posed by Celtic fans chanting, "Where were you on
the Twelfth?" during a pre-season friendly match against
Celtic at
Craven Cottage. Healy subsequently apologised profusely for any offence he may have caused and signed many autographs for Celtic fans after the game. He remained out of favour with Roy Hodgson, who regarded his signings
Andy Johnson and
Bobby Zamora ahead of Healy in the pecking order. Despite this sum he would never start a league game for the "Black Cats". Healy made his debut for Sunderland four days later in the League Cup and marked by scoring the winning goal in extra time against
Nottingham Forest. Having scored in his Leeds, Fulham, Sunderland, Doncaster and Northern Ireland debuts, he also marked his first Rangers appearance with a goal, coming off the bench to add the final goal of a 6–0 win over
Motherwell on 12 February. Upon the expiry of his contract he signed a new one-year deal with the club, tying him to the
Ibrox club until the end of the
2011–12 season. On 2 January 2012, Healy scored his second goal for the club, again against Motherwell, with the opener of a 3–0 win. His third goal for the club came the following week, when he scored the first of a 4–0 victory over
Arbroath in the
Scottish Cup. He netted his third league goal of the season for the "Gers" in a 4–0 win over
Hibernian on 28 January, and got his fourth goal in a 4–1 victory over
Dunfermline Athletic on 11 February. He left Ibrox at the end of the 2011–12 season following the expiration of his contract.
Bury He signed a one-year deal with League One side
Bury in August 2012. He had previously been linked with a return to Preston North End, but manager
Graham Westley rejected the chance to re-sign the striker after finding that Preston fans still resented Healy for the manner of his departure eight years ago. He made a scoring debut for the "Shakers" on 25 August, converting a penalty in a 2–2 draw with
Coventry City at the
Ricoh Arena. He was limited to one goal in his 19 games in the
2012–13 campaign as Bury were relegated into
League Two. He was one of 16 players released at the end of the season. Unable to find a club after his release and struggling with persistent ankle injuries, Healy announced his retirement from football on 3 December 2013. On 31 July 2014, Healy played for
Glenavon in a 5–0 loss in a pre-season friendly against his former club
Leeds United. The match was part of Glenavon's 125th anniversary celebrations. ==International career==
