RENTON Patrick Kerney Color Rush Jersey , Wash. (AP)Seattle Seahawks strong safety Kam Chancellor said scans on his injured neck have shown no improvement and declared it was ”time for the next chapter.”Chancellor had been awaiting further clarity on his neck, which he injured in a game against the Arizona Cardinals in November. In a posting on his Twitter account Sunday night, Chancellor said his latest scans ”showed no healing.””I’ve played through all types of bruises and injuries at a high level. But this one, I just can’t ignore,” he wrote.Chancellor never used the word ”retirement” in his statement, which may have been deliberate. Chancellor signed an extension through the 2020 season last August which contained guaranteed money in case of injury. An official retirement could open up the possibility of forfeiting some of that money. Chancellor’s extension was signed before the start of last season and included a total of $25 million in guaranteed money.Chancellor was named to four Pro Bowl teams (2011, 2013-15) and was twice a second-team All-Pro selection (2013, 2014). He appeared in 109 career games for Seattle with 93 starts after being selected in the fifth-round of the 2010 NFL draft.Seattle had foreshadowed the severity of Chancellor’s situation without providing specific details regarding his injury. In his post Germain Ifedi Color Rush Jersey , Chancellor said he was told paralysis was a possibility.”When the doctors told me what was going on in (November), I could feel my heart drop to my stomach. The stiffness in my neck and the images I saw had me at one of my lowest points as a man, because football is all I knew outside of serving the Lord,” Chancellor wrote. ”To walk away from the game by choice is one thing, to walk away from the game because of the risk of paralysis is another.”Chancellor was part of Seattle’s first draft under the leadership of coach Pete Carroll and general manager John Schneider. After a year as a backup, Chancellor became a starter in 2011 and quickly emerged as one of the hardest-hitting, most intimidating safeties in the NFL. Chancellor was also the emotional leader of a locker room and defense full of big personalities.Chancellor’s announcement – while expected by most – is the latest in an offseason filled with changes for Seattle that has seen Richard Sherman, Michael Bennett and Cliff Avril depart. Safety Earl Thomas has also been absent from Seattle’s entire offseason program as he seeks a new contract with his current deal up after the 2018 season.Seattle did address replacing Chancellor in the offseason by signing Bradley McDougald to a new deal after he filled in following Chancellor’s injury last season.— The battle over who will serve as Russell Wilson‘s backup in Seattle this season will continue throughout Thursday night’s preseason finale against the Oakland Raiders.Both Geno Smith and Paxton Lynch have missed a game due to injury over the first three weeks of preseason games. Smith had a cyst surgically removed from his knee and missed the second game against the Minnesota Vikings. Lynch was concussed from a shot to the head by Vikings cornerback Holton Hill and missed the third game against the Los Angeles Chargers on Saturday. Each will have a final impression to make against the Raiders before roster cuts this weekend.“They’ve both had their moments. Certainly Marshawn Lynch Color Rush Jersey ,” head coach Pete Carroll said Wednesday. “They’ve basically taken care of the ball really well. It’s just an important factor. They can both run the offense. I’m really anxious to get another assessment here, especially on Paxton. He’s going to play in this game. Those two guys, he and Geno will split it and see how they do.”Smith has completed 14 of 27 passes for 175 yards while being sacked three times. He’s also rushed for 45 yards and a touchdown on nine carries.Lynch’s numbers are marginally better. He’s completed 17 of 30 passes for 176 yards and a touchdown while being sacked once. He’s also rushed for a touchdown, gaining 37 yards and on six carries.Smith has been the steadier option throughout training camp while Lynch has had the greater variance with more highlight plays but more mistakes as well.The Seahawks have rarely had three quarterbacks on their active roster during Carroll’s tenure as head coach. B.J. Daniels spent time on the active roster, primarily as a receiver, after initially playing quarterback for the team. But carrying three quarterbacks on the 53-man roster has not been a regular occurrence.With that in mind, Smith and Lynch will have one final audition to make their case they deserve the job against the Raiders Thursday night.
