Walt Anderson, the NFL vice president responsible for training and development, confirmed the news of Madsen’s death in a statement. The cause of death was not immediately known.
“Karl Madsen has been a responsible player in the NFL for more than two decades, first as a highly respected official on the field before moving to the replay role beginning in 2009,” Anderson said in a statement.
“A wonderful friend and colleague, Karl’s love for football and dedication to management was always present, generously sharing his time to mentor young administrators in clinics across the country. An Air Force veteran, Karl had an immense spirit and will that we miss so much.”
According to the NFL Network, Madsen died while “on his way home” from a Titans game in Nashville.
Madsen served 12 seasons as a field officer from 1997-2008, according to NFL.com. The following year he became a re-official. He worked in three playoff matches as a referee and four other matches as a replay official.
