Detroit Lions linebackers coach Kelvin Sheppard is reportedly a candidate to land a defensive coordinator position in the NFL.

Detroit’s offensive line coach joins two other, younger candidates as those Mike Macdonald’s talked to twice for Seattle’s OC job.

ESPN's Dan Orlovsky and The Athletic’s Derrik Klassen share their perspectives on two Seattle Seahawks offensive coordinator candidates.

A report from @mzenitz indicates that the New England Patriots are targeting Lions' DL coach Terrell Williams to be their new DC. He worked closely with Patriots HC Mike Vrabel in Tennessee. Another change to the coaching staff could be on the horizon @DetroitPodcast

Source says Lions OL coach Hank Fraley is scheduled to interview in-person today with the Seahawks for their offensive coordinator position. This will be the second interview for Fraley with the Seahawks.

The Patriots interviewed Vikings assistant OC/assistant QBs coach Grant Udinski for their offensive coordinator job yesterday, per sources. Udinski’s very valuable in Minnesota—and considered a rising star in the field. The 28-year-old is also a finalist for the Seattle OC job.

The Lions have already lost offensive coordinator Ben Johnson to the Bears, while defensive coordinator Aaron Glenn looks to be on track to land the Jets’ head coaching gig.

Now entering their third week of interviews, the Seahawks may need to hasten their offensive coordinator search with new competition entering the mix.

With Johnson heading to Chicago and Mike Vrabel already in New England, five head coaching vacancies remain. The media could not be loaded, either because the server or network failed or because the format is not supported. The Jets, Saints, Jaguars, Raiders and Cowboys are still in the hunt.

Lions head coach Dan Campbell said on Monday that he's prepared to lose offensive coordinator Ben Johnson and defensive coordinator Aaron Glenn to head coaching jobs, but those might not be the only departures from the team's staff.

According to reports, the New England Patriots want to hire Detroit Lions defensive line coach Terrell Williams as their next defensive coordinator.
