Bears Sign LB Costanzo To 2-Year Deal

CHICAGO (CBS) -- The Chicago Bears have signed free agent linebacker and special teams player Blake Costanzo to a two-year deal.

Costanzo, 27, played with the San Francisco 49ers last season. He has appeared in 61 games in five seasons, with Buffalo, Cleveland and San Francisco -- mostly on special teams.

In 2009, he was named to Sports Illustrated's All-Pro team as a special teamer for the Cleveland Browns.
