Longtime linebacker DeMeco Ryans has been promoted to the role Ken Norton Jr. had for less than a week with the 49ers in January.
Ryans will coach inside linebackers, including prominent pupil Reuben Foster, in 2018. Johnny Holland, the team's linebackers coach in 2017, has a new title: run game coordinator and outside linebackers coach.
The 49ers originally hired Norton, the former Raiders defensive coordinator, to be their inside linebackers coach. Less than a week after that announcement was made, however, the Seahawks asked Norton to be their defensive coordinator, and he accepted the offer.
Ryans, 33, is one of several San Francisco coaches with ties to the Houston Texans.
