The Cardinals, not surprisingly, are looking at cornerbacks at the start of free agency.
Former Eagles cornerback Roderick Hood arrives Sunday night for a visit with the team, his agent said Friday. Former Rams cornerback Travis Fisher is also scheduled to visit Tempe Sunday.
The Cardinals want to add corners to compete with starter Eric Green opposite Antrel Rolle. The Cards aren't expected to bring back their own free-agent cornerbacks: David Macklin and Robert Tate.
Meanwhile, a Dallas source said the Cowboys are negotiating with Cardinals free-agent lineman Leonard Davis, meaning Davis' tenure in Arizona may be nearing its end. Davis also has a visit scheduled with the Washington Redskins Saturday.
Davis could play either guard or tackle for the Cowboys, depending on how the rest of free agency plays out. Davis has long wanted to play in Dallas, which is close to his hometown of Wortham, Texas.
The Redskins would use Davis to replace guard Derrick Dockery, who will be leaving in free agency himself.
Davis said he wouldn't mind returning to Arizona, but both Dallas and Washington are expected to offer better deals than what the Cards would offer.
Another potential Cardinals' target, fullback Ovie Mughelli, was taken off the market Friday when he signed with Atlanta.
