Blackmon, 30, signed on with the Seahawks as a free agent back in March. However, he was unfortunately among their final roster cuts a little over a week ago.
In 2014, Blackmon appeared in eight games and recorded 30 tackles, one sack, and a forced fumble during the 2014 season. Pro Football Focus has him rated as the No. 85 cornerback out of 108 qualifying players.
