The Cardinals hired three more assistant coaches Friday, including Billy Davis to coach linebackers after Davis served as the 49ers’ defensive coordinator the past two seasons.
Davis’ hire means another holdover assistant — Frank Bush, who had been assistant head coach and linebackers coach under Dennis Green — has been let go.
The Cards had recently denied permission for a second straight year for the Texans to talk to Bush, but now Bush is free to go to Houston. Texans head coach Gary Kubiak, a good friend of Bush after both coached in Denver, wanted Bush on his staff last year as co-defensive coordinator.
The Cards also hired special teams coach Kevin Spencer, who worked with new head coach Ken Whisenhunt in Pittsburgh, and strength and conditioning coach John Lott. Lott comes from the Cleveland Browns.
With Bush’s departure, the Cardinals still have four holdover assistants in limbo: defensive coordinator Clancy Pendergast, offensive line coach Steve Loney, safeties coach Rick Courtright and receivers coach Mike Wilson.
Whisenhunt is expected to interview potential offensive line coach Jeff Davidson, an NFL source said Friday. Davidson also called plays for the Browns this past season. Davidson was on the Browns’ staff with Lott.
Pendergast remains in the mix for defensive coordinator, but the fact Whisenhunt has not yet named him to his staff would seem to indicate a desire to explore other options.
