NFL Notes: Kansas City Chiefs extend Charles

The Kansas City Chiefs signed running back Jamaal Charles to a five-year contract extension, continuing their plan to lock up their impressive core of young players.

Charles confirmed the signing on his Twitter account, but the team declined to comment on the contract or even say if Charles had signed an extension.

Reportedly, the deal guarantees $13 million for Charles, who went into Sunday’s game at San Diego leading the Chiefs in rushing. His 1,137 yards were third in the NFL and he had the highest per-carry average at 6.2 yards.

Rodgers’ status unclear next week

For the second time this season, Aaron Rodgers is recovering from a concussion following a Green Bay loss.

The Packers lost their quarterback late in the second quarter against Detroit, shortly after Rodgers was hit on back-to-back plays. He was slow getting up after being hit by Amari Spievey and Landon Johnson at the end of an 18-yard scramble. Green Bay took a timeout, then Rodgers was sacked on the next play.

Rodgers was not made available to reporters afterward, and he was not in the locker room when it was open to the media, so his status for next weekend’s game at New England is unclear.
