Early AFC West notes


San Diego cornerback and punt returner Antoine Cason could miss several weeks of the preseason because he is having surgery to repair a severely broken ring finger. He is expected to be ready for the season.

The Chiefs officially signed former Sam Diego linebacker Brandon Siler.

The Oakland Tribune expects Zach Miller to re-sign with the Raiders very soon.

Defensive end Tyson Jackson knows this is a big season for him in Kansas City. He was the No. 3 overall draft pick in 2009 and, so far, has given the team limited contribution. This could be a make-or-break year for Jackson in Kansas City.

ESPN is going to reveal a new way to gauge a quarterback’s true value on Friday. It’ll be a fun system to follow throughout the season to see exactly what kind of impact each AFC West quarterback has on his team.

Tackle Matt Light has agreed to stay in New England. The Chiefs were connected to him.
