Born in Glasgow, Gordon Greer joined local youth team Port Glasgow Juniors, before starting his professional career with Clyde in 2000.
Making 30 appearances for the second-tier Scottish club, Greer was the subject of a successful £250,000 bid from Blackburn Rovers, who at the time, were plying their trade in the Premier League.
Unable to pave a way into regular contention in England’s top-tier, and being limited to just a single Cup appearance, Greer joined Stockport County in the third-tier in 2003, playing three league matches in the process.
Heading back for Scotland after leaving Blackburn, Greer joined Kilmarnock in the Scottish Premiership, where he accumulated over 100 appearances in four years.

In an attempt to breakthrough regularly in the English game, Doncaster Rovers emerged as his next destination in 2007, however, after just 12 appearances in two years, he joined Swindon Town.
Proving to be his most productive spell yet, the Scotsman played 46 league games for The Robins during their League One campaign, before joining Brighton & Hove Albion in the same division.
Greer appeared 32 times for The Seagulls in his debut season on the south coast, a year where they were promoted back to the Championship.
180 Championship appearances later, and Greer departed for his second spell with Blackburn.
The central defender appeared 21 times for the Lancashire club during the 2016/17 campaign, before heading back to Kilmarnock.
In two more years with the Scottish Premiership club, Greer appeared 20 times, before hanging up his boots in October 2018.
Greer also made it to international level with Scotland. He made 11 appearances for his national side between 2013 and 2016.
Greer has remained in football ever since departing, but it is not the coaching route that he has gone down.
Instead, it is the scouting path that he is on, and he has since returned to Brighton to take a role as a senior scout at the club.
