That's why the team is expected to sign either David Bowens, Derrick Ham, Jeff Posey or Al Wallace as soon as Monday.
The Dolphins also worked out three defensive backs this week, among them former Dolphin Jerry Wilson, and a move could be made at that position soon after the Dolphins place Trent Gamble on injured reserve, as expected.
The other two DBs who worked out were former Chargers cornerback Fahkir Brown and former University of Wisconsin standout Donny Brady.
Coach Dave Wannstedt didn't put travel restrictions on his players during this weekend's bye week, but they better be on hand for a Monday morning team meeting.
"They better back Sunday night," Wannstedt said. "I'l be anxiously standing at the door (Monday). The way flights are now, getting canceled, you better be sure."
