The New Orleans Saints will hire Dallas Cowboys assistant Sean Payton to his first NFL head coaching job, a team official familiar with the decision said. A formal announcement is expected today. Payton has been a quarterbacks coach for three seasons under Bill Parcells in Dallas. He also held the title of assistant head coach. Before that, he was a New York Giants assistant, a stint that included that team’s NFC Championship in 2000. Assistant head coach Mike Singletary will stay with the 49ers after he was removed from the list of candidates for the Lions’ coaching job. Harper update The wife of Indianapolis Colts cornerback Nick Harper will not face a felony battery charge for cutting him with a kitchen knife, a judge ruled. Hamilton County Prosecutor Sonia Leerkamp said the judge apparently did not allow the battery charge because Nick and Daniell Harper both claimed the stabbing was accidental. However, Daniell Harper, 31, still faces a criminal recklessness charge. She was released on $5,000 bond Tuesday after spending the weekend in the jail. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

The former Patriots defensive coordinator, who turns 35 on Thursday, becomes the youngest head coach in the league. Terms of the deal weren’t known but it is believed he will get between $2 million and $2.5 million per year over five years. The baby-faced Mangini takes over for Herman Edwards, who left for Kansas City last week. Norv Turner, fired as coach of the Oakland Raiders two weeks ago, moved across San Francisco Bay to become the 49ers’ offensive coordinator. The Patriots promoted linebackers coach Dean Pees to defensive coordinator, replacing Mangini.
