RENTON, Wash. (AP) — The Seattle Seahawks have added depth to their secondary by acquiring cornerback Mohammed Seisay from the Detroit Lions for an undisclosed 2016 draft pick. Seattle announced the trade on Sunday. The Seahawks had an open spot on their 90-man roster after releasing defensive tackle Tony McDaniel in a salary cap move. The draft pick going back to Detroit is expected to be a late-round selection. Seisay appeared in 13 games last season for Detroit as a rookie.
