Mike Greenberg will replace Sam Ponder as host of “Sunday NFL Countdown” on ESPN, the network announced Tuesday. Ponder was laid off last week along with the show’s analyst, Robert Griffin III. Greenberg, 57, is best known for “ Mike & Mike ,” the hit sports-talk radio show with former NFL player Mike Golic that enjoyed an 18-year run before ending in 2017.

Greenberg and Golic were inducted into the National Assn. of Broadcasters Hall of Fame in 2016 and the National Radio Hall of Fame in 2018. As the current host of daily “Get Up” on ESPN and “Greeny” on ESPN Radio, Greenberg is already busy.

He also hosts the NFL Draft on ESPN. Greenberg is also a prolific author. His first book, a self-deprecating account of his life as a sports fan and husband published in 2007, “Why My Wife Thinks I’m an Idiot,” spent five weeks on the New York Times’ Best Sellers List and was nominated for a Quill Award.

Three years later, Greenberg and Golic wrote “Mike & Mike’s Rules for Sports and Life,” which reached No. 3 on the New York Times’ Best Sellers List. He also has published two novels, “All You Could Ask For” and “My Father’s Wives,” and two years ago co-authored a collection of short sports essays, “Got Your Number: The Greatest Sports Legends and the Numbers They Own.

” In his new gig on Sunday mornings, Greenberg will be joined by NFL insider Adam Schefter and former players Randy Moss, Tedy Bruschi, Rex Ryan and Alex Smith. Reporting on-.
