The Dallas Cowboys have hired former Tampa Bay defensive coordinator Monte Kiffin as the replacement for Rob Ryan.
The team announced the move on its website Friday, a day after the 72-year-old Kiffin was at team headquarters to interview with coach Jason Garrett and owner Jerry Jones.
The hiring of Kiffin means the Cowboys will switch back to the 4-3 defense after going to the 3-4 under Bill Parcells in 2005.
Kiffin hasn't coached in the NFL since ending a 13-year run in Tampa in 2008. He spent the past few years coaching in college with his son, Lane Kiffin, at Tennessee and Southern California.
At Tampa, Kiffin's defenses frequently were among the league's best, and the Buccaneers won the Super Bowl with him after the 2002 season.
