AFC West notes

Pro Football Talk reported Kansas City running back Jamaal Charles is not expected to play until the regular season. He suffered a minor foot strain in practice Monday. Keeping him out just a precaution makes sense. Why risk an injury in August?

U-T San Diego reports the Chargers signed receiver Seyi Ajirotutu on Friday. He has been in San Diego in the past. While the Chargers need depth at the position, Ajirotutu still likely will be a bottom-of-the rotation player.

The San Francisco Chronicle reports Oakland defensive end Lamarr Houston likely will miss his second consecutive preseason game Friday night at New Orleans. He is coming back from an undisclosed injury.

The Chargers waived-injured receiver Danario Alexander. It was a procedural move. He is a pending free agent, thus, it is highly unlikely another team will claim him and take on his 2013 salary with him out for the year.
