The Raiders continued to run into roadblocks in their quest to finalize a trade for Falcons cornerback DeAngelo Hall.

It was thought that when Hall arrived in Oakland on Wednesday it would be to sign a contract that would make him the league's highest-paid cornerback and clear the way for him to be sent to the Raiders for second- and sixth-round draft choices.

But after spending 4½ hours with owner Al Davis, Hall emerged Wednesday night without an agreement. And if a deal is not consummated Thursday, it's possible the Raiders might end the talks and move on, a club source said Wednesday night.

Hall has expressed a desire to join the Raiders during his talks with many of the team's core players. But his representatives and the team are said to be at odds over the structure of the contract.

Hall, who would team with Nnamdi Asomugha in Oakland to form one of the league's top cornerback tandems, has one year remaining on his rookie contract and it's highly unlikely any team would trade for him without first coming to terms on a new multiyear contract.

Hall remained in Oakland overnight and is scheduled to talk with club officials again Thursday.
