According to a source, Dallas has received permission from the Jacksonville Jaguars to speak with Campo, who has served as the team's secondary coach and assistant head coach the last three seasons. Multiple sources indicated that Campo would like to return to Dallas, where he has family.

Todd Bowles, the Cowboys' secondary coach from 2005 to 2007, left Dallas last week to join new Dolphins coach Tony Sparano's staff. Bowles will serve as secondary coach and assistant head coach in Miami.

After Steelers quarterback Ben Roethlisberger and Patriots quarterback Tom Brady combined to complete 79 percent of their passes for 599 yards in the Jaguars' two playoff games, addressing the secondary became an off-season priority for coach Jack Del Rio.

Donnie Henderson, a former defensive coordinator with the Detroit Lions and New York Jets, was hired by Jacksonville on Friday as a defensive assistant. The move coincided with the Jaguars granting the Cowboys permission to speak with Campo.

Henderson's specific role is undefined, but he is expected to coach the secondary. Campo is one of two assistant head coaches on the Jaguars staff, with Mike Tice also holding that title. Campo is one of two secondary coaches employed by Jacksonville, the other being Alvin Reynolds.

The Cowboys were denied permission to speak to Falcons secondary coach Emmitt Thomas at last week's Senior Bowl. Thomas, who served as interim head coach when Bobby Petrino left for Arkansas, has been promoted to assistant head coach.

Dallas also showed interest in Jerry Gray and Dennis Thurman, secondary coaches with the Redskins and Ravens. Both remain under contract with their teams.

Campo originally came to Dallas in 1989 as secondary coach and served in that capacity under Jimmy Johnson and Barry Switzer before becoming defensive coordinator in 1995.
