RENTON, Wash. (AP) — The Seattle Seahawks are releasing Justin Britt and D.J. Fluker in a major overhaul of their offensive line that clears significant salary cap space. A person with knowledge of the move told The Associated Press that Britt had been informed he is being released, ending six seasons with the Seahawks. Fluker posted on Twitter that he had been released after two seasons as Seattle’s starting right guard. The two moves were not unexpected. Seattle will save about $12 million combined in salary cap space between the two roster moves, most of that belonging to Britt.
