The Chicago Bears have given Lance Briggs a one-year contract extension that locks up the veteran linebacker through 2014.  Financial terms of the deal were not disclosed, but going into last season, Briggs approached the team seeking a raise over the $3.65-million and $3.75-million in base salaries he was set to receive in 2011 and 2012, and asked for a trade if the Bears couldn't accommodate the request.  The 31-year-old University of Arizona product has been named to seven straight Pro Bowls and led the Bears in tackles for the fourth time in his career last season.
