Jay Glazer of FoxSports.com first reported that Haden interviewed Del Rio, a former USC All-American linebacker, during the Broncos' bye week.
Del Rio, former head coach of the Jacksonville Jaguars, began the season as the Broncos' defensive coordinator, a position he also held in 2012. AP reported that the Broncos confirmed that Haden contacted Broncos executive vice president John Elway to seek permission to speak with Del Rio. The interview reportedly took place Nov. 1.
Three days later, Del Rio was named the Broncos interim coach after Coach John Fox underwent heart surgery.
