Kirkland, WA (SportsNetwork.com) - The Seattle Seahawks announced on Monday the signing of free agent cornerback Will Blackmon, as well as contract extensions for restricted free agent linebacker Mike Morgan and unrestricted free agent tight end Anthony McCoy.

Blackmon had spent the previous two seasons with the Jacksonville Jaguars before being jettisoned on Feb. 26.

The Rhode Island native and Boston College product recorded 30 tackles and one sack over eight games, including four starts, with the Jaguars last season before being placed on injured reserve with a fractured finger.

The 30-year-old started eight games as Jacksonville's nickel back in 2013 and finished that season with 40 tackles and one interception over 15 contests.

Blackmon has played in 66 games over eight NFL seasons with Green Bay, the New York Giants and Jacksonville, and was a member of the Giants' Super Bowl XLVI champion team in 2011. He had been a member of the Seahawks during training camp in 2013 before the Jags snagged him following an early round of cuts.

Morgan participated in 16 games last year, but made his presence best known on special teams, returning a Doug Baldwin-blocked punt for a score. The Southern Cal product was originally signed as a free agent in 2011, and has played in 53 games over the last four seasons for the Seahawks.

McCoy's 2014 season was over before it began thanks to a torn Achilles tendon suffered in training camp. That was on the heels of a season-ending Achilles tear in 2013.

The 27-year-old Californian totaled 31 receptions for 437 yards and three touchdowns in 32 games over the 2011 and 2012 seasons.
