Teams across the NFL were allowed to start talking to upcoming free agents on Tuesday and the Chicago Bears have already reached some agreements. 

We've heard over the last weeks that the Bears are trying to trade Jordan Howard and that they'll likely lose Bryce Callahan to free agency. 

Bears GM Ryan Pace is already working on their replacements. 

According to Ian Rapoport the Bears signed running back Mike Davis to a two year deal with $6million. 

Rapoport adds the Bears have also signed corner back Buster Skrine who can play the nickel, a sure indication that Callahan is gone.
