Brandon Fisher, son of former Tennessee Titans coach Jeff Fisher, has been added to the Detroit Lions coaching staff.

The younger Fisher will work as an assistant to the defensive coaching staff. The announcement was made today (Thursday).

Brandon Fisher stepped in to help the Titans last season after offensive coordinator Mike Heimerdinger was diagnosed with cancer during the season and moved from the sidelines to the coaching box.

A blog by Paul Kuharsky at the NFL Nation said that Jeff Fisher wanted to add his son to his Titans’ staff for the 2011 season amd reportedly that was a breaking point for Titans’ owner Bud Adams who doesn’t believe in nepotism. Jeff Fisher was fired by the Titans in January.

Brandon Fisher was a standout linebacker at the University of Montana where he played in 54 games (30 starts) and finished with 169 tackles.

Lions coach Jim Schwartz came to Detroit after spending nine seasons on the Titans coaching staff under Jeff Fisher.
