Born in Newtownards, County Down,[1] Fettis started his career with Glentoran before playing for Ards from 1988 to 1991, making 65 appearances in all competitions for the club.
[2] He was a firm fans' favourite whilst at Hull City, and on occasion found himself playing as a striker due to injuries at the club, and bagged himself a couple of goals in the process.
He was sold back to Hull by new manager Chris Brass in 2003; York dropped out of the league a year later, returning for the 2012–13 season.
Fettis was signed by Bury on a 12-month deal in June 2006,[3] but broke his right arm in a League Cup defeat against former side Sheffield United on 19 September.
[10] In 2019, after the sudden departure of Emilio Alvarez from the club, Fettis temporarily stepped up to first team duties to support senior goalkeeping coach Richard Hartis.
