ALLEN PARK -- Just one day after the Senior Bowl, the Detroit Lions administration went right back to work.
The team announced Sunday afternoon that head coach Rod Marinelli will retain five of the team's assistant coaches, including nine-year special teams coach Chuck Priefer and defensive assistants Don Clemons and Phil Snow.
Snow, however, will be promoted to the team's linebackers coach.
The Lions also officially announced the signing of Donnie Henderson as the team's defensive coordinator.
Although not confirmed, Marinelli will also add Larry Beightol, formerly of Green Bay, as his offensive line coach and former Texans offensive assistant Kippy Brown as the receivers coach.
Detroit is expected to name its offensive coordinator by the end of next week.
Marinelli will become the sixth Lions head coach -- interim or otherwise -- that Priefer has worked under since joining the team under former head coach Bobby Ross. Priefer's assistant, Stan Kwan, will also return along with coaching assistant Adam Gase.
