Terms of the deal weren’t disclosed.
Fisher arrives in Seattle to help fill a void early in training camp. Starting cornerback Marcus Trufant remains out indefinitely with what Seahawks coach Jim Mora has called a minor back injury, and Fisher brings experience as a possible replacement. He has started 74 NFL games over seven seasons.
The Seahawks have three other cornerbacks with starting experience — Kelly Jennings, Ken Lucas and Josh Wilson.
Fisher spent the last two seasons with the Detroit Lions before being released. He was selected by the St. Louis Rams in the second round of the 2002 NFL Draft and played five seasons with them before joining the Lions.
Fisher has 336 tackles, nine interceptions and two touchdowns in his career.
