CINCINNATI — Hue Jackson needed only a few weeks to land another job in the place where he’s always welcomed.

The Bengals hired Jackson on Tuesday as a special assistant to head coach Marvin Lewis as he tries to resurrect Cincinnati’s historically bad defense. Jackson was fired by the Cleveland Browns last month after he won only three games in three seasons as head coach.

As soon as Cleveland let him go, the Bengals showed an interest in Jackson, who begins his third stint with them.

In his latest role, he’ll help Lewis — a close friend — to try to fix the defense and save the season. Cincinnati (5-4) has lost three of its past four games and is on pace to give up the most yards in a season in NFL history. The Bengals have allowed 500 yards in three straight games, a first for any team in the Super Bowl era.

They fired defensive coordinator Teryl Austin on Monday, with Lewis taking over as defensive coordinator in addition to his head coaching duties. Lewis said on Monday that there was a plan to help him do both jobs, but didn’t get specific.

The Bengals talked to Jackson about becoming Lewis’ special assistant, and he readily accepted the position.

“I have a great comfort level with Hue and his ability to assist me with the day-to-day responsibilities on defense, including analyzing our opponents and helping me on game days with the players and defensive coaches,” Lewis said.

Lewis hired Jackson in 2004 — his second season in Cincinnati — as receivers coach. He spent three years in the job before moving to the Falcons.
