Atlanta ? The Atlanta Falcons have reached agreement to hire San Francisco defensive coordinator Jim Mora as the team’s head coach, a source said Thursday night.

The Falcons will make an announcement this morning, said a source close to the negotiations who spoke on condition of anonymity.

Mora, the son of former New Orleans and Indianapolis coach Jim Mora, was a finalist for the San Francisco job last year before the 49ers hired Dennis Erickson.

Mora met with Falcons owner Arthur Blank in his Buckhead office Wednesday for the first time. He interviewed the previous week in Atlanta with Falcons general manager Rich McKay but had not yet met Blank.

Dan Reeves was fired Dec. 9 as the Falcons’ coach, and defensive coordinator Wade Phillips took over on an interim basis. Atlanta finished 5-11, but Phillips went 2-1.

The hiring was first announced Thursday by SI.com.

Mora, 42, has worked the last five years as the 49ers’ defensive coordinator.

He spent the 1997 and ’98 seasons coaching San Francisco’s secondary and held the same job with San Diego in 1986-88.

Mora’s first job came with the Chargers in their pro personnel department. He never worked for his father.

In addition to drawing interest from Atlanta, Mora also interviewed with the Chicago Bears, and his name was mentioned among those in line for the Oakland job.
