Pre-game notes from Oakland

Posted by ESPN.com’s Bill Williamson

OAKLAND -- It’s getting chippy already on a hot day by the bay:

About 45 minutes prior to the game, there was verbal sparring between several Denver and Oakland players. The Denver players seemed to be the aggressors. A few officials separated the large group of players (about 25 players per team) and then two teams went to separate sides of the field to stretch.

Denver rookie running back Knowshon Moreno is playing. He was questionable with a groin injury.

Denver receiver Brandon Stokley is playing. He was questionable with a thigh injury.

Oakland safety Michael Huff is starting for the injured Hiram Eugene.

Oakland receiver Javon Walker is inactive after being active last week. You have to wonder if he’ll ever make an impact in Oakland.

Denver linebacker/fullback Spencer Larsen is missing his third straight game with a shoulder injury.

Denver 2007 first-round pick Jarvis Moss, a linebacker, is a healthy scratch.

It is nearing 90 degrees in Oakland. It will likely be several degrees warmer on the field. It could be an advantage for Denver, which is wearing white shirts and pants, while Oakland is wearing its black jerseys.
