Senn spent the past six years with the Indianapolis Colts (2008-09) and Carolina Panthers (2009-13), appearing in 83 games with seven starts. For his career, Senn has racked up 88 tackles, one interception, two pass break-ups and four forced fumbles.
Senn, a former special teams’ captain for the Panthers, has made 49 lifetime tackles on special teams. He played in 14 games for Carolina last season and registered six special teams' stops.
Senn could be earmarked to replace veteran special teams ace Blake Costanzo, who is a free agent. The Bears have made no attempt to re-sign Costanzo, according to a source with direct knowledge of the situation. Costanzo led the Bears with 17 special teams tackles in 2013.
