CBS chief Sean McManus said in a statement that "Dan and Shannon are true Hall of Famers on the field and in front of the camera. As they pursue other professional opportunities, we thank them for their hard work and dedication and wish them nothing but the best."

Marino leaves after 13 seasons with CBS, while Sharpe joined for the 2004 season, giving him a decade on the show.

CBS says recently retired star tight end Tony Gonzalez will join the network as an analyst for "The NFL Today" as well as other programming.
