Carl Madsen, who had worked for the NFL as an official for more than 20 years, died on Sunday. He was 71.
According to NFL.com, Madsen died on his way home from Sunday's game between the Kansas City Chiefs and Tennessee Titans, where he was working as a replay official.
While details are hazy on Madsen's death, the Nashville Police Department told TMZ that early signs indicate Madsen suffered "a medical emergency" while driving on I-65 North. A spokesperson reportedly said officers answered a call about a motorist blocking a traffic lane and found Madsen unconscious at the scene.
Chest compressions were immediately administered once Madsen was removed from the vehicle, per the report, but he ultimately died after being transported to a nearby hospital. His exact cause of death remains unknown.
An Air Force veteran, Madsen spent 12 years as an on-field official from 1997 to 2008 before transitioning to his replay official role. He was reportedly tied with Paul Weidner as the league's most experienced replay official.
"Carl Madsen was an NFL officiating fixture for more than two decades, first as a highly respected on-field official before transitioning to a replay role beginning in 2009," NFL senior VP of officiating training and development Walt Anderson said in a statement. "A terrific friend and colleague, Carl's love of football and dedication to officiating was ever-present, as he generously shared his time to mentor young officials at clinics across the country. A veteran of the Air Force, Carl had a tremendous spirit and will be greatly missed."
NFL Referees Association president Scott Green also released a statement to Pro Football Talk:
“Carl will be missed by those who worked with him on the field and in replay,” Green said. “He had a nickname among his fellow officials of “Big Country” which was not only related to his size but to his big personality as a warm and generous man.”
