The Las Vegas Raiders fired coach Josh McDaniels and general manager Dave Ziegler, the team announced Tuesday night.

“After much thought about what the Raiders need to move forward, I have decided to part ways with Josh and Dave,” owner Mark Davis said in a statement. “I want to thank them both for their hard work and wish them and their families nothing but the best.”

Reached by phone and asked to elaborate on the reason for the firings, Davis told ESPN, “No comment at this time.”

The Raiders named linebackers coach Antonio Pierce as their interim head coach. The team also said that current assistant general manager Champ Kelly will serve as interim GM. In announcing those promotions, the organization said it is committed to undergoing “a comprehensive search” for a head coach and general manager “once the season is complete.”

Davis would not say who would take on offensive playcalling duties, as that was McDaniels’ job. Phone calls to McDaniels and Ziegler were not returned.
