Shead, who was an exclusive rights free agent, has been a versatile piece of the Seattle secondary since joining the club as an undrafted free agent out of Portland State following the 2012 draft. The 26-year-old native of Palmdale, Calif. made his first career start in 2014 in place of injured safeties Kam Chancellor and Jeron Johnson, who has since signed with the Washington Redskins in free agency. Shead finished the year with two passes defensed and seven tackles, four of which came against the Oakland Raiders in that first career start.
