The Chicago Bears officially announced the signing of free agent linebacker Brian Iwuh.

Terms of Iwuh's contract were not disclosed, and first-year tight end Kevin Brock has been released to fit Iwuh on the 80-man off-season roster.

Signed by the Jacksonville Jaguars as an undrafted free agent out of the University of Colorado in 2006, Iwuh appeared in 58 games for the Jaguars over the last four seasons, totaling 83 tackles, 45 of which came as a core member of Jacksonville's special teams units.

Iwuh participated in the Bears' weekend mini-camp on a tryout basis.
