Evening AFC West news and notes

Posted by ESPN.com’s Bill Williamson

Kansas City is heading into the practice week with four quarterbacks on the roster even with Matt Cassel healthy. The backups are Brodie Croyle, Tyler Thigpen and Matt Gutierrez. Carrying four quarterbacks is a rarity in the NFL. But if there is an injury elsewhere, Thigpen could be decent trade bait. So, the Chiefs may want to keep the three backups for awhile.

To make room for defensive tackle Alfonso Boone, the team released defensive end Andre Coleman, who has been bouncing back and forth from the practice squad to the 53-man roster.

The Chargers announced they have 2,500 tickets to sell by Thursday’s deadline to avoid a local television blackout for Sunday’s game against visiting Miami.

Former Denver running back Ryan Torain is healthy and ready to sign elsewhere. Several teams have expressed interest in Torain. He was cut by Denver after spraining his knee. He has had three significant injuries in the past year.

Veteran tackle Jon Runyan remains unsigned. He tried out with the Chiefs two weeks ago.

The Shawne Merriman-Chad Ochocinco Twitter spat has continued. They two went at it Twitter style during the summer. The Chargers and Bengals play Dec.20.
