Jackson, Gradkowski injury updates

OK conspiracy theorists, it looks like Vincent Jackson was originally injured in practice Friday and aggravated a calf injury Sunday night. So, it doesn’t appear that he was faking an injury in order to avoid playing for a team he doesn’t want to play for. Meanwhile, the San Diego Union Tribune reported that he has a strain and he likely won’t play against Oakland on Sunday.

Jackson’s time to help the Chargers in 2010 may be shrinking, but he is still expected to be healthy to play at some point in December. The earliest opportunity likely being against visiting Kansas City on Dec. 12.

The Raiders are waiting for the results of an MRI on the injured shoulder of quarterback Bruce Gradkowski. The shoulder kept him out for five weeks earlier this season.

Gradkowski will surely miss some time and there is a chance he will be out for an extensive period. So it looks like this is Jason Campbell’s team again as the 5-6 Raiders try to stop a two-game losing streak Sunday at San Diego. Campbell has been benched twice this season in favor of Gradkowski, but there’s a strong possibility Campbell will finish the season unless he fails again and the team has to turn to No. 3 quarterback Kyle Boller.

Again, this all leads me to think Oakland will be looking for a new starting quarterback heading into 2011.

Denver coach Josh McDaniels said cornerback Andre' Goodman, rookie receiver Demaryius Thomas (ankle) and safety Brian Dawkins will not play at Kansas City on Sunday due to injuries.

Even though he was mad at McDaniels 15 days ago, Kansas City coach Todd Haley opted to steer clear of the videotape scandal as the Chiefs prepare to face the Broncos on Sunday.

In this ESPN.com video, analyst Trent Dilfer praised San Diego quarterback Philip Rivers for his play in the Chargers' 36-14 win at Indianapolis on Sunday night.

Meanwhile, ESPN Stats & Information further examines Peyton Manning’s struggles against the Chargers defense in the game. In a radio interview, San Diego linebacker Kevin Burnett talks about the handling of Manning, which included an interception return for a touchdown.

A Bay Area columnist believes Oakland coach Tom Cable will be fired after the season.

The blackout for Sunday’s game against Oakland has been lifted and it will be shown on local television in San Diego. The Chargers will wear their power blue jerseys for the first time this season in the game.
