Kevin Boss TE KC Feb 19 '13
Chiefs released TE Kevin Boss.
Signed to a three-year, $9 million deal early in free agency last year, Boss suffered a season-ending concussion in Week 2. He finished with just three catches. Boss has a long and winding concussion history, suffering no fewer than four during his NFL career. The former Giant and Raider could be at the end of the line after failing to gain medical clearance last season.
