The Seahawks bolstered their depth at cornerback Monday by signing free agent cornerback Will Blackmon, who was briefly a Seahawk in the summer of 2013 before being cut at the end of training camp. He spent the past two seasons with Jacksonville, where he started 12 of 23 games.
Blackmon, 30, a six-foot, 200-pounder from Boston College, was a fourth-round pick in the 2006 draft by Green Bay, when Seahawks GM John Schneider worked for the Packers. He spent four years with the Packers before two more with New York Giants.
The Seahawks need help in the secondary with the pending departure of CB Byron Maxwell, who will sign with Philadelphia when the free agent signing period begins at 1 p.m. Tuesday. Two backup DBs, Jeremy Lane (arm/knee) and Tharold Simon (shoulder), had to undergo surgeries this off-season.
The Seahawks also extended the contracts of TE Anthony McCoy and LB Mike Morgan.
McCoy has had Achilles tendon tears in each leg that have kept him out the past two seasons. Seattle drafted McCoy in the sixth round (185th overall) of the 2010 draft. He played in 34 games with 14 starts before his injuries. He has 31 career receptions for 437 yards and three touchdowns. After starting TE Zach Miller was cut, McCoy, if healthy, could be in the mix for a starting job.
Morgan signed with Seattle as an undrafted free agent in 2011. He has played in 53 games with one start, totaling 21 tackles (13 solo), 19 special teams tackles and a 25-yard TD return on a blocked punt vs. Dallas in October. He has also played in eight postseason games.
The Seahawks also declined to tender a contract to WR Bryan Walters, who was a restricted free agent. A graduate of Juanita High in Kirkland, Walters is now a free agent because the Seahawks relinquished their right of first refusal in the event of an offer from another team.
Walters was the Seahawks’ top punt returner last season, with 27 for 207 yards. He also had six receptions in the regular season and played in all three postseason games.
The Seahawks made a qualifying offer to WR Ricardo Lockette by the Monday deadline for exclusive free agents. The team also made the same offer to CB DeShawn Shead, keeping both for another year.
