First quarter notes from San Diego

Posted by ESPN.com’s Bill Williamson

It's 7-7 early in the second quarter:

Oakland quarterback JaMarcus Russell threw a bad interception on his second pass attempt of the game. San Diego cornerback Antonio Cromartie picked off the badly overthrown ball. Russell was benched last week against the Jets in the second quarter after throwing two interceptions and losing a fumble.

So, the Russell watch is on.

The Raiders are being very conservative with Russell. On a drive that started on their own 11, the Raiders ran three straight times and were forced to punt. Russell is only going to throw when necessary. What’s the point? Take him out if that’s the case.

The Chargers run defense is not looking great. Oakland can run all day if it chooses to.

San Diego inside linebacker Tim Dobbins was just taken off the field on a cart with a knee injury. He is playing for Kevin Burnett, who has ankle injury. This would be a big loss for San Diego.

It didn’t take long for receiver Malcolm Floyd to make an impact for the Chargers as he overtook Chris Chambers as a starting receiver. Floyd caught a 53-yard pass from Philip Rivers on the Chargers’ first offensive play of the game. On the next play, running back LaDainian Tomlinson scored on a 6-yard run. Tomlinson is running very strong so far.

Oakland cornerback Chris Johnson intercepted a ball that went off of Vincent Jackson’s hands. It set up Oakland's score.

Fullback Mike Tolbert is becoming San Diego’s short-yardage back. He converted a first-down on third and short.

San Diego linebacker Shawne Merriman is playing very well against the run. Still no sacks, though.
