The San Francisco 49ers will now officially begin their search for a new defensive coordinator, with DeMeco Ryans agree to terms on a six-year deal with the Houston Texans to become the next head coach.

Amongst those the 49ers will be pursuing, according to ESPN's Adam Schefter, is Washington Commanders' defensive backs coach, Chris Harris, who is one of the top up-and-coming assistants in the NFL.
In 2022, the Commanders ranked fourth in the NFL in pass defense, giving up just 191.3 yards per game.
Harris was expected to take a job as the Titans defensive passing game coordinator, but with the Ryans news, could be in line to take a different job.
However, that's not the only name on the list for San Francisco.
Per Mike Garafolo, the 49ers also plan to talk to ex-Panthers interim head coach Steve Wilks after he was passed over for the permanent job in Carolina for Frank Reich.
Wilks was the Panthers' defensive pass game coordinator before being promoted to interim coach when Matt Rhule was fired mid-season. He was previously the defensive coordinator in Carolina and Cleveland and was the head coach of the Cardinals in 2018.
