AFC West notes

The Raiders signed FB/RB Jamize Olawale from Dallas’ practice squad to their 53-man roster. He will be given an audition for the future in practice and perhaps in games down the stretch. He is a rookie from North Texas.

Oakland defensive tackle Richard Seymour (knee/hamstring) remains out of practice Tuesday as the Raiders prepare to face Denver on Thursday night. Seymour has missed four straight games. The fact that it's a short week and he is not practicing is not a good sign that Seymour will be ready to face the Broncos.

There appears to be a strong chance the Chargers will face starting Pittsburgh quarterback Ben Roethlisberger on Sunday. He has been out for the past few weeks.

U-T San Diego reports the Chargers are signing interior offensive lineman Colin Baxter to help an injury-ravaged offensive line. He has previously been with the Chargers.

Cornerback Stanford Routt signed with Houston. He was cut by the Chiefs last month.
