"Free agent LE Tyson Jackson says he "just started negotiations" with the Chiefs.
Jackson played both end spots last season for the Chiefs and turned his career around under new coach Andy Reid and DC Bob Sutton. He recorded 34 tackles and a career-high four sacks while grading out as a top-ten 3-4 end against the run. The former No. 3 overall pick should have plenty of suitors in free agency."
