DETROIT (AP) -- The Detroit Lions have bolstered their linebacker group with Christian Jones and Devon Kennard.
Detroit signed both unrestricted free agents on Thursday.
Jones and Kennard were starters for the Chicago Bears and New York Giants, respectively, in parts of four seasons. Jones had a career-high 84 tackles last season in Chicago and matched career highs with two sacks, a forced fumble and a recovered fumble. Kennard had four sacks last season with the Giants and 9 1/2 sacks in his career.
The Lions made a major move on the first day of free agency, releasing tight end Eric Ebron. The 2014 first-round pick would have earned $8.25 million this season if he was on the roster past 4 p.m. Wednesday.
