The Cincinnati Bengals will have to wait a couple of weeks to formally hire their head coach, but they have already secured the services of their next offensive coordinator.

According to Oakland Raiders head coach Jon Gruden during his media availability at the Senior Bowl, Brian Callahan will be moving on from his position of quarterbacks coach in Oakland to join the Bengals as their new offensive coordinator:

“Here's an announcement for you, Brian Callahan's no longer with us,” Gruden said, according to NFL.com’s Nick Shook. “He's gonna go with the Cincinnati Bengals, believe he's gonna be the offensive coordinator of the Bengals. And I'm really proud of him, happy for him, happy for this opportunity. We're short-handed right now. We've lost a lot of quarterback guys over the years and they've all gone on — a lot of them have done great things and I'm sure Brian will do the same.”

At the moment, Los Angeles Rams quarterbacks coach Zac Taylor is expected to join the Bengals as their head coach, but with the Rams currently preparing for Super Bowl LIII, the team must wait an additional two weeks to make the hiring official. In the meantime, it looks like Taylor has begun filling out his staff:

Brian Callahan is the son of Bill Callahan, the current offensive line coach for the Washington Redskins. According to JP Finlay of NBC Sports, the elder Callahan is also expected to leave his post in Washington for the Bengals once the Super Bowl is over.
