Evening AFC West news and notes

Posted by ESPN.com's Bill Williamson

The San Diego Union-Tribune reports San Diego running back LaDainian Tomlinson said Wednesday night that he is optimistic that he and the Chargers will come to an agreement on a restructured contract.

Still, Tomlinson said he realizes the NFL is a business. It seems that Tomlinson is preparing himself for whatever happens. But he remains hopeful to stay in San Diego. The two sides have been trying to come to an agreement for several days.

Meanwhile, Oakland is still pursuing Buffalo center Duke Preston.

The Oakland Tribune has a transcript of Oakland coach Tom Cable's press briefing today regarding linebacker Marquis Cooper, who is missing at sea.

The Raiders are visiting with Khalif Barnes, an athletic tackle who the team has been considering signing for days. There could be movement on the Barnes front in Oakland on Thursday. The team is concentrating on Barnes and not Pittsburgh's Marvel Smith at this point.

The Raiders and Chargers are both vying for the services of Dallas linebacker Kevin Burnett, who could make a decision on where he'll play at any time.

Even though Seattle receiver Bobby Engram departed Kansas City without a contract, the two sides could still make a deal.
