Following are several of the whispers we've been hearing from around the AFC West:
• After injuring his knee in the season opener, Chiefs DE Tyson Jackson was finally able to return to practice during the team's Week Four bye. Although Jackson said he has not been discouraged about sitting out two consecutive victories, the fact that the defense excelled without him does not bode well for the 2009 first-round pick's playing time upon his return to game action. When he'll be active again on game day remains unknown, but in the meantime sixth-year player Shaun Smith has been effectively filling in for him.
• Switching QB Tim Tebow from second to third on the depth chart in Week Three was a temporary move. The way we hear it, the Broncos will play the matchups when it comes to deciding who will be QB Kyle Orton's backup. Brady Quinn will likely get the call against more complex defenses because the team likes the fact that he has previously played against top NFL defenses. The former Notre Dame standout figures to be active the next two weeks against the Ravens and Jets.
• The Chargers have had an unprecedented string of bad luck at long-snapper this season. After David Binn, who had missed just one game in his career of 16-plus years, injured his hamstring in Week One and was put on injured reserve, the team has since signed two long-snappers who also have suffered season-ending injuries. San Diego signed its fourth long-snapper of the season earlier this week, veteran Ethan Albright, and hopes he will make it through more than one game.
• Raiders DL Richard Seymour has been on the injury report every week since the season opener with a hamstring injury, and the team will be very cautious about how it uses him in practice until the hamstring stops bothering him. Seymour admitted that the injury has limited him in games this season.
