RENTON - The Seattle Seahawks made five additional roster moves Tuesday to trim their roster to the 75-man roster limit.

Only one such move involved having to part ways with a player.

The team terminated the contract of CB Will Blackmon Tuesday. Blackmon, a seven-year veteran, just wasn't going to have a spot on a deep roster and perhaps at the team's deepest position. Blackmon should find another job in the league without too much difficulty.

In addition, the Seahawks moved WR Percy Harvin (hip), DE Greg Scruggs (knee) and CB Tharold Simon (foot) to the reserve physically unable to perform list and LB Korey Toomer (knee) to the reserve non-football injury list.

By moving the four players to the reserve list, they no longer count against the team's roster limit and are ineligible to return until after Week 6 of the regular season.

DE Chris Clemons remains on the active/PUP list for the time being. He can still be placed on the reserve list prior to the start of the season or activated and kept on the 53-man roster.

--Injury Updates

DT Brandon Mebane did not practice Tuesday after injuring his groin in practice on Monday.

In addition, DT Jordan Hill (biceps) and DT Tony McDaniel (undisclosed) sat out practice. It further lessens the Seahawks' depth along the defensive line with McDaniel sidelined as well. Head coach Pete Carroll did not speak on Tuesday so an update on his status was not yet available.

WR Sidney Rice (knee), WR Stephen Williams (undisclosed), FB Michael Robinson (illness) and DE Cliff Avril (hamstring) also were sidelined.

WR Bryan Walters did some limited work but didn't apear to take part in team activites. He's been battling a hamstring injury the last several weeks.

--Practice Notes

Miami Heat head coach Erik Spoelstra attended Seahawks practice on Tuesday and spoke to the team before practice.

With all the injuries along the defensive line, DT Jaye Howard worked with the first-team defense.
