Karl Ravech, one of ESPN’s most prominent on-air voices for more than three decades, and NFL insider Tom Pelissero were laid off as part of the network’s latest round of cuts Tuesday, according to sources briefed on the moves.The layoffs are the first since ESPN finalized its acquisition of NFL Network in January, and most of the dismissals were expected to take place at NFL Network with a large contingent behind the scenes, according to the sources, who spoke on the condition of anonymity to discuss a sensitive matter. ESPN purchased NFL Network as part of a series of agreements that gave the league a 10 percent stake in the network. ESPN has spent the past six months sorting out how to make all the pieces from its bases in Bristol and New York coordinate with NFL Network’s Los Angeles operation.In an internal memo Tuesday, ESPN chairman Jimmy Pitaro said the network has “made significant progress integrating the NFL assets that we acquired into ESPN.”“While most of the job impacts are tied to the acquisition, we will also notify colleagues in other parts of the company today that their positions have been impacted,” Pitaro said.On Monday, ESPN laid off NFL analyst Ryan Clark as part of the cuts. ESPN declined further comment.ESPN also severed ties with former NFL MVP Cam Newton, longtime SportsCenter stalwart David Lloyd, injury expert Stephania Bell, former All-Pro linebacker and talk show host Bart Scott, as well as NFL Network analyst Charles Davis. News of the Bell, Lloyd and Scott layoffs were first reported by Front Office Sports; Outkick initially mentioned the Newton decision.
