The vastly experienced defender linked up with Rovers on a free transfer until the end of the current campaign.
As part of the deal, Brown will spend time working with Damien Johnson and David Dunn, coaching Rovers’ Under-23s, who he has represented on three occasions in the Premier League 2 this season.
One of the game’s most decorated defenders, Brown started his career with Manchester United, joining the club’s esteemed Academy at the age of 12.
He made his first team debut in a 3-0 victory over Leeds United at Old Trafford in May 1998 and helped United win the Treble the following season.
Brown would go on to make over 350 appearances for his boyhood club, winning a further four Premier League titles, three League Cups, a second FA Cup and the Champions League again in 2008.
After 15 years as a professional at Old Trafford, the defender joined Sunderland in July 2011 on a four-year deal.
He made his debut in a 1-1 draw against Liverpool at Anfield and would go on to make 87 appearances for the Black Cats, helping them to secure their Premier League status in each of the last five seasons.
Brown has enjoyed success on the international stage with 23 caps for England.
