(Renton, WA)  --  Seattle Seahawks safety Kam Chancellor appears ready to keep his contract holdout going.  ESPN's Adam Schefter, citing an anonymous source, reports Chancellor is prepared to extend the holdout into the regular season.  ESPN quoted Chancellor's agent as saying the two sides have made no progress in negotiations since the holdout began.  In 2013, Chancellor signed a four-year, 28-million-dollar contract extension that made him one of the NFL's highest-paid safeties.
