Kush appeared in eight games with four starts last year in his first season with the Bears after being claimed off waivers from the Rams following final cuts.
Kush's four starts in 2016 came in place of injured Pro Bowler
Prior to joining the Bears, Kush played three games with the Chiefs in 2013 and seven contests with the Rams in 2015. He also has spent time with the Buccaneers, Panthers and Texans. The 6-4, 315-pounder was selected by the Chiefs in the sixth round of the 2013 draft.
Kush's signing leaves 27 Bears players who are due to become free agents when the new league year begins March 9. The 17 unrestricted free agents are set to include receivers
The others are tackle
Two restricted free agents will be defensive back
Unrestricted free agents are free to sign with any NFL team without any draft choice compensation owed to the original club; restricted free agents can sign an offer sheet with another team but their original team has the opportunity to match it or receive draft pick compensation; and exclusive free agents can only negotiate and sign with their own team.
Beginning Wednesday and continuing through March 1, NFL teams can place a franchise tag on one free agent-to-be. Jeffery is believed to be the Bears' only potential candidate for the designation, but it is unclear whether they will tag the veteran receiver for the second straight season. If they do, Jeffery would be guaranteed $17.5 million for the 2017 season.
