Brown formerly played for Queens Park Rangers, Salisbury City, Hayes & Yeading United and Bristol Rovers, spending seven seasons with the latter club and amassing 321 appearances before joining Portsmouth and then AFC Wimbledon.

[3] He made fourteen appearances for the club, including twelve starts, before returning to Loftus Road before the end of the calendar year.

On 24 April 2010 he made his debut in the Football League, replacing Tamás Priskin as a substitute in a 1–0 win over Barnsley at Oakwell.

The left-back played an important role in QPR's pre-season of 2009–10 and was subsequently given his first squad number in light of the lack of full-backs at the club.

[7] Brown returned to Church Road on transfer deadline day in a loan deal until the end of the 2010–11 campaign, snubbing a similar move to League One side Leyton Orient.

[10] On 6 August 2011, Brown made his Bristol Rovers debut in the opening game of the season, live on Sky Sports, against AFC Wimbledon.

[17] Brown scored his first goal of the 2016–17 season in an FA Cup first round tie against Crawley Town, striking a superb shot from 35 yards into the bottom left corner.

[20] Following the 1–1 draw with Wigan Athletic, it was confirmed that Brown would leave Rovers at the end of the season, having made over 321 appearances for the club, in order to be closer to London.

Manager Darrell Clarke confirmed his last game, the forthcoming home fixture with Gillingham, would see Brown take the captain's armband.
