Brown joined Manchester United at the age of nine, having previously played for Fletcher Moss Rangers. After making his way through United's youth teams he was awarded his first professional contract by the club in the summer of 2009.

Brown, like Gill, made his debut on 2 October 2010 in a 0–1 defeat to Morecambe. On 25 October 2010, the pair returned to Manchester United after the expiration of their month's loan despite Bradford's willingness to extend their stay. On 16 August 2011, he joined Doncaster Rovers on a month's loan. He made his debut on the same day, coming on as an 85th-minute substitute for Kyle Bennett in Doncaster's 1–0 home defeat by Nottingham Forest. Brown returned from his loan spell at Doncaster on 10 September 2011 and after a couple of impressive displays in the reserves, he was included in the first-team squad for the League Cupthird round tie against Leeds United, however he was an unused substitute on the night. On 2 March 2012, Manchester United agreed for Brown to spend a one-month loan spell at Oldham Athletic. On 3 April 2012, Brown extended his loan deal with the club until the end of the season.

Although the loan was intended to last the entire season, Manchester United recalled Brown in January 2013 after he fell down the pecking order at Coventry; his last appearance came in the league against Oldham Athletic in September 2012. On 25 February 2013, Manchester United agreed for Brown to spend the rest of the season on loan to Ipswich Town. At the end of the 2012–13 season, he was released by Manchester United.

Despite still being contracted to Watford, Brown went on trial at League One side Barnsley in July 2014 playing in some of their pre-season fixtures. On 31 July 2014, Brown duly signed for Barnsley from Watford for an undisclosed fee on a one-year deal with the option of a second. After a spell with Bury, he linked up with Sheffield United in September 2016 following a successful trial.
