Rovers swooped to bring Dann back to his native north-west, joining from Birmingham City on deadline day in August 2011.
Liverpool-born, Dann started his professional career with Walsall before impressive displays saw the young defender clinch a move to Coventry City in January 2008.
In the summer of 2009 Dann made the move to Birmingham City where he played a key role as the Blues gained promotion to the Premier League.
The step-up to the Premier League proved no problem with Dann forming an impressive central defensive partnership with Roger Johnson in the Birmingham defence until a hamstring injury curtailed his campaign in 2010-11.
That summer Rovers signed the central defender, Dann putting pen-to-paper on a four-year-deal.
A near ever-present at the heart of the Rovers defence for the last two years, the former England Under-21 international was handed the captain's armband during the second half of the 2012-13 season.
