NEW YORK (AP) - The New York Jets have reached an agreement with Rex Ryan to make the Baltimore defensive coordinator their head coach, a person with knowledge of the deal told the Associated Press.

The person, who spoke on the condition of anonymity because the four-year deal was not yet finalized, says it was expected to be done in the next few days.

Ryan, 46, replaces the fired Eric Mangini and takes 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.

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