AFC West notes

Agent David Canter announced on Twitter that injured Kansas City Chiefs linebacker Brandon Siler has signed a one-year extension. He had signed a one-year deal in the summer with the Chiefs after leaving San Diego.

Siler had a chance to win a starting job, but he blew out his Achilles on the final play of a preseason practice. It was Kansas City's second re-signing in two days. They signed kicker Ryan Succop to a five-year extension Friday.

Jon Gruden said he will remain at ESPN after a report stated he could have ended up in St. Louis with Chargers general manager A.J. Smith if Smith is fired in San Diego.

Tim Tebow will get a chance for a different kind of payback on Kyle Orton Sunday.
