The Seattle Seahawks made more player moves Tuesday to get down to the league mandated 75 player limit.

Veteran cornerback Will Blackmon had his contract terminated by the Seahawks Tuesday as the team trimmed its roster. The veteran defensive back and kick returner was hoping to catch on with Seattle after having sat out the 2012 season with injuries,

Wide receiver Donavan Kemp was released.

Placed on the reserve/physically unable to perform list were wide receiver Percy Harvin, defensive lineman Gregg Scruggs and rookie cornerback Tharold Simon. Linebacker Korey Toomer was put on the reserve/non-football injury list.

Harvin, Scruggs and Simon will have to sit out the first six games of the regular season and then will have a three-week window to practice before the club must decide whether to add them to the 53-man roster.

Harvin had recent hip surgery, while Scruggs had knee surgery during the offseason and Simon has been sidelined with a foot injury.

The Seahawks have one more pre-season game on Thursday, hosting the Oakland Raiders.  Teams must reduce their rosters to 53 by midnight Saturday.
