AFC West news and notes

Posted by ESPN.com’s Bill Williamson

The Chiefs signed linebacker David Herron and cornerback Mike Richardson on Wednesday.

Both players have a history with New England and now Kansas City general manager Scott Pioli. Herron was with the Patriots for one week in 2007 and Richardson was a sixth-round pick of New England in 2007.`

The Chiefs took a look at former Green Bay tackle Mark Tauscher. He is an interesting player. He suffered a major knee injury last December. If healthy, he could be a good fit for Kansas City, which needs tackles. The Chiefs tried out former Philadelphia tackle Jon Runyan three weeks ago.

Oakland brought back return man Justin Miller. He was cut in September, but was brought back because Oakland has several injuries.

Former Oakland running back Louis Rankin was signed to Seattle’s practice squad. Oakland cut him Saturday.

Former Denver running back Ryan Torain worked out in Miami. It was his first workout since Denver cut him after he had a knee injury in August.

In an ESPN.com MVP watch, San Diego quarterback Philip Rivers is 6th and Denver linebacker Elvis Dumervil is 10th.
