The burly, mustachioed color man who followed a Hall of Fame football career with a three-decade stint in the broadcast booth is hanging up his microphone. Dan Dierdorf will retire from CBS after this season, his 43rd connected to the National Football League. After a 13-year stint as an offensive tackle for the St. Louis Cardinals, he began his announcing career with CBS Radio in 1984, moving to the TV side the following year. He left CBS in 1987 for ABC, where he did color for Monday Night Football until 1999 and also covered NCAA games, boxing and the 1988 Winter Olympics. He has been with CBS for the past 14 years. Dierdorf’s often brusque, call-it-like-he-sees-it style earned him plenty of detractors — snarky L.A. sports radio legend Jim Healy famously referred to him as “Dan Dierdork” — but in 2008 he became one of only four Pro Football Hall of Fame players to receive the Hall’s Pete Rozelle Radio-Television Award for excellence in broadcasting.
