Bly played in the NFL for 12 seasons. His first four were spent in St. Louis before he came to Detroit for four years. He started in 54 games for the Lions and was selected to the Pro Bowl in 2003 and 2004. The Lions traded him to the Broncos in 2007, and he played in Denver for two years before spending 2009 with the 49ers.
The Lions signed Bly again in July 2010, but he was released during the final round of roster cuts.
