He began his career at Gillingham where he made over 100 appearances, before joining up with Premier League side Blackburn Rovers in 2006.

[2] Brown began his career playing youth football as a defender for Fisher Athletic before converting to a goalkeeper at the age of 14.

Charlton coach Gary Stevens later told Brown that "a year ago you were a waste of space, but you've come on and proved a lot of people wrong".

After being recommended by Dean Kiely to Sheffield United's assistant manager Kevin Blackwell, Brown earned a trial at Bramall Lane.

However, Brown eventually wasn't offered a contract as Warnock was looking for a more experienced alternative to first choice goalkeeper Simon Tracey.

During the trial he played in seven youth fixtures and one reserve match for the club and was eventually handed a two-and-a-half-year contract at the Priestfield Stadium.

[3] After regularly appearing upon the bench, Brown was handed his senior debut on 5 March 2002, where he played the full 90 minutes of a 2–1 victory over Grimsby Town.

[3] Brown's first cap for Wales Under-21s came in a 2–1 defeat to Finland in a 2004 UEFA European Under-21 Championships qualifying group stage game.

[28] Brown was first named in the senior Wales squad for friendlies against a Basque XI and Trinidad & Tobago in May 2006,[29] although he ended up pulling out of the first match due to the birth of his first child.

[31] Brown would then wait another six years for his third and final senior cap which came in Chris Coleman's first game in charge as Wales manager.

[32] Brown retired from playing at the end of the 2014–15 season to take up the goalkeeping coach position at former club Gillingham in the summer of 2015.

[34] The appointment was made permanent shortly afterwards, with Brown signing a contract until 2019, but he was unable to prevent the team's relegation to Thai League 2.
