Afternoon free agency update

Posted by ESPN.com's Bill Williamson

The San Diego Union Tribune reports the Chargers will not pursue receiver Terrell Owens or safety Roy Williams. Both players have been cut by Dallas.

While many folks are concentrating on Owens ending up in Oakland, Williams could be a possibility. He grew up near Oakland and the Raiders could use a safety.

The Oakland Tribune reports the Raiders recently visited with quarterback Kyle Boller. The former Cal standout would come in as a backup quarterback if signed.

The Chiefs are looking at free agents Keary Colbert, Keith Davis and Travis Daniels.

Oakland free-agent return man Justin Miller visited with the Titans. Miller made an impact when he was claimed off waivers by the Raiders.
