The NY Post is reporting the death of Carl Madsen.
Mr. Madsen was a long-time NFL official: he worked on-field from 1997 to 2008, then worked as a replay official from 2009.
He worked the game between the Titans and the Chiefs on Sunday. According to the report, he was driving home to Mississippi when he had some kind of medical problem. The police responded, pulled him out of the car and did first aid, and transported him to a hospital where he passed away.
He was 71. Our condolences to his family.
