The Hall of Fame linebacker, currently a San Francisco 49ers assistant head coach, will interview today with team owner Jerry Jones. He'll become the eighth candidate considered to replace Bill Parcells.
Singletary, the 49ers' assistant head coach for defense, has interviewed twice previously for head coaching jobs. Earlier this month, he spoke with Atlanta Falcons owner Arthur Blank, who decided to hire Bobby Petrino to replace the ousted Jim Mora. A year ago, Singletary was interviewed for the Detroit Lions coaching vacancy that went to Rod Marinelli.
Singletary also remains under consideration for the 49ers defensive coordinator position, for whom head coach Mike Nolan has interviewed Chargers linebackers coach Greg Manusky, Dave Campo and Donnie Henderson. Nolan has said that he favors hiring an experienced NFL coordinator, hoping to free himself up from some of the play-calling duties in order to focus on game management matters.
Neither Singletary nor Manusky has experience as an NFL coordinator. Both had 12-year NFL playing careers. Manusky has been an NFL assistant for five years, while Singletary just completed his fourth NFL season as an assistant.
Best known for his ferocious play with the Chicago Bears, Singletary is a Houston native who played college football at Baylor. He's been coaching in the NFL since 2003, spending two years with Baltimore and the last two with the 49ers.
Another 49ers assistant, offensive coordinator Norv Turner, has been viewed as the front-runner in Dallas, but he returned to the Bay Area following his interview Sunday.
Singletary, 48, was hired by the Baltimore Ravens and spent two seasons guiding the inside linebackers. Nolan was the Ravens' defensive coordinator, and when he became the head coach in San Francisco, Singletary followed. He was assistant head coach for linebackers, then named assistant head coach for defense last season.
The Cowboys already have hired Jason Garrett and are considering him for the head coaching job or likely will make him offensive coordinator. Defensive coordinators Wade Phillips of San Diego and Gary Gibbs of New Orleans also are being considered.
Jones also has talked to three members of Parcells' staff, including Todd Bowles, who is black. Singletary retired after the 1992 season and was inducted into the Hall of Fame in 1998.
