Dunn joined Rovers as an eight year old and made his debut in 1998, making nearly 170 appearances before being sold to Birmingham in 2003.

After four seasons in the Midlands he returned to his boyhood club and played just shy of 200 times for the club during his second spell.

At the end of last season he was released by the club, and joined League One side Oldham Ahtletic initially as a player.

However, following the sacking of Darren Kelly as manager in September last year, Dunn was put in charge permanently after initially being appointed on an interim basis.

His first managerial stint was to be short lived though, and he was sacked in January after just 20 games in charge.

He will be working under Rovers manager Paul Lambert as well as former West Brom manager Alan Irvine, who is part of the backroom staff.
