NEW YORK— Baltimore defensive coordinator Rex Ryan was hired as the coach of the New York Jets on Monday, a day after the Ravens lost in the AFC championship.

The 46-year-old Ryan replaces the fired Eric Mangini, taking over a team that started last season 8-3 but missed the playoffs with quarterback Brett Favre after losing four of its last five games.

The Jets announced the hiring, but released no other details. The contract is for four years, a person with knowledge of the deal told The Associated Press. The person spoke on condition of anonymity earlier Monday because the deal had not been announced.

Ryan will be formally introduced at a news conference Wednesday at the Jets' facility in Florham Park, N.J.

The deal was finalized Monday afternoon after Jets owner Woody Johnson and general manager Mike Tannenbaum flew down to Baltimore in the morning to iron out the details, Jets spokesman Bruce Speight said.
