The 49ers have an offensive coordinator for coach Chip Kelly’s offense.

According to Adam Schefter of ESPN, the 49ers have hired Lions running backs coach/run game coordinator Curtis Modkins to run Kelly’s offense. It’s unclear how much running of the offense Modkins will do; by all appearances and indications, Kelly will have his hands firmly on the wheel.

Modkins joined the Lions in 2013. Before that, he spent three seasons with the Bills, one with the Cardinals, one with the Chiefs, and more than a decade at the college level. Under former Buffalo coach Chan Gailey, Modkins served as offensive coordinator but like Kelly in San Francisco, Gaily ran the offense.

Eri Mangini continues to be the defensive coordinator in San Francisco. With Mike Vrabel turning down the job, Mangini could end up sticking around.
