RENTON, Wash. (AP) — The Seattle Seahawks have cleared a chunk of salary cap space by waiving safety Tedric Thompson and releasing veteran tight end Ed Dickson. Both moves were expected after each player seemed to fall out of favor with the Seahawks. Their releases will clear more than $5 million worth of cap space for Seattle. Thompson started 16 games over the past two seasons. Dickson did not play in a game last season due to knee troubles.
