The San Francisco 49ers are on the search for a defensive coordinator once again after firing Nick Sorensen following just one season in that role.

The San Francisco 49ers could bring back a former defensive coordinator who knows the team well, with the goal of helping veterans like Nick Bosa and others in the 2025 season. The San Francisco 49ers definitely need a boost on defense.

But if you expected sweeping change, that will have to wait another year if anything like 6-11 happens again. The 49ers dismissed defensive coordinator Nick Sorensen and special teams coordinator Brian Schneider but will promote passing game specialist Klay Kubiak to offensive coordinator. With Shanahan still calling the plays.

While Kyle Shanahan promoted Klay Kubiak to San Francisco 49ers offensive coordinator earlier this week, the NFL requires all teams to interview at least two external minority candidates.

San Francisco 49ers head coach Kyle Shanahan announced that Klay Kubiak will be the team’s new offensive coordinator. According to Shanahan, Kubiak has been doing the job unofficially for the past two years.

Bad news for Kyle Shanahan, who had planned to name Klay Kubiak as OC for the upcoming NFL season. It appears a rule prevents him from receiving that kind of promotion. Kyle Shanahan is doing everything he can to ensure the San Francisco 49ers have a successful 2025 season.
