New Washington Redskins head coach Ron Rivera reportedly hired Jack Del Rio as his defensive coordinator Wednesday, according to ESPN's Adam Schefter.
It is unclear who else will be part of Rivera's staff, but JP Finlay of NBC Sports Washington reported Bill Callahan, who served as interim head coach following the firing of Jay Gruden, and most of the defensive staff will not return.
Finlay added that offensive coordinator Kevin O'Connell is among the holdover assistants who will interview with Rivera but noted that none of them "definitively" have a job.
