Denver coach John Fox remained hospitalized Sunday as he awaits aortic value replacement surgery in North Carolina.
Fox spoke with Broncos executive vice president John Elway by phone Sunday to discuss logistics during his absence, including who will serve as interim head coach.
All signs point to defensive coordinator Jack Del Rio being that man, although team spokesman Patrick Smyth said that as of Sunday afternoon no decision had been made.
The 58-year-old Fox will have surgery in a few days and will miss several weeks.
Fox had been told earlier about his heart condition and was hoping to put off the operation until February. On Saturday, Fox became dizzy playing golf near his offseason home in Charlotte and was taken to a hospital, where tests revealed he couldn't wait any longer to have the surgery.
