Holcomb interviewed with the team on Thursday, and he's the third known candidate to have interviewed for the position vacated when Warren Belin was fired earlier this month. The hire was first reported by ESPN's Adam Schefter.
Holcomb is the first Panthers' position coach hired in the past two weeks who did not have ties to the organization. The offensive coordinator, quarterbacks coach, special teams coordinator and receivers coach were all promoted from within the club. Jim Skipper, the team's former running backs coach, was brought back last week after being fired by the Titans.
Former Atlanta Falcons defensive coordinator Brian VanGorder and former Panthers linebacker coach Bill Davis were also interviewed for the job.
Holcomb has never been a position coach in the NFL. He was a low-level assistant for four seasons with the Giants, the organization with which new Panthers general manager Dave Gettleman spent a decade and a half.
He inherits a linebacking corps that includes Jon Beason, Thomas Davis, James Anderson and strong candidate for 2012 NFL Defensive Rookie of the Year, Luke Kuechly, who led the league in tackles in the 2012 season.
