Mornhinweg spent the past 10 years as an assistant with the Philadelphia Eagles, including the past seven as the team's offensive coordinator.
He was previously the head coach of the Detroit Lions, and was also an assistant with San Francisco and Green Bay.
Sparano was fired after one season as the Jets' offensive coordinator as New York finished 30th in overall offense.
Mornhinweg is expected to bring a more wide-open passing approach to the Jets, who have relied more often on a "Ground-and-Pound" philosophy under Rex Ryan. It is uncertain if starter Mark Sanchez, owed 8.25 million in guarantees, or backup Tim Tebow, expected to be traded or released, will remain with the team.
Browns hire Horton as defensive coordinator
BEREA, Ohio -- The Browns considered Ray Horton for their head coaching vacancy. They hired him to fill another one.
Horton, who spent the past two seasons as Arizona's defensive coordinator, was named to the same position with the Browns on Friday. The 52-year-old recently interviewed with Browns owner Jimmy Haslam and CEO Joe Banner before the team chose Rob Chudzinski as its sixth coach since 1999. Horton replaces Dick Jauron, who was not retained on Chudzinski's staff.
"We are truly excited that we were able to get someone of Ray's caliber as our defensive coordinator," Chudzinski said. "He possesses a great deal of experience as a player, position coach and coordinator in the NFL and has been part of some of the top defenses in the league throughout his career. He is an extremely talented coach and I know that he will work very well with the young nucleus of players we have on defense."
Under Horton last season, Arizona's defense ranked second in the NFL in interceptions and third-down efficiency. Horton, who was considered for Arizona's head coaching job before the team hired Bruce Arians, has 19 years of experience as a pro assistant.
Cowboys add Rod Marinelli to staff
IRVING, Texas -- The Dallas Cowboys have hired former Detroit head coach Rod Marinelli as defensive line coach.
The Cowboys reported the move on the team's website Friday. Marinelli was the defensive coordinator under Lovie Smith with the Chicago Bears, but decided not to stay on the staff of Smith's replacement, Marc Trestman.
The move reunited Marinelli with new Dallas defensive coordinator Monte Kiffin. The two were on the same staff in Tampa Bay.
Kiffin replaced Rob Ryan, who was fired last week.
Marinelli was the head coach of the Lions when they went 0-16 in 2008. He was 10-38 in three seasons with Detroit before getting hired as defensive line coach by Chicago. He spent the past three years running the Bears' defense.
