OWINGS MILLS, Md. — The Baltimore Ravens have replaced offensive coordinator Marty Mornhinweg with Greg Roman, who will continue to oversee the evolution of Lamar Jackson as the team’s starting quarterback.

The 46-year-old Roman spent the past two seasons as Baltimore’s assistant head coach/tight ends coach. In that role, he worked with the team’s quarterbacks and played an integral part in the Ravens’ transition from Joe Flacco to Jackson in late November.

Mornhinweg, who ran the Baltimore offense for three years, was offered a different post on the team “but has decided to move on,” coach John Harbaugh said Friday.

Roman has been a key component in developing the Ravens’ running game. Under his direction, Baltimore moved from 28th in the NFL in rushing in 2016 to 11th last year and second this season.

Before beginning his second stint with the Ravens in 2017, Roman spent two years as Buffalo’s offensive coordinator and four years in the same role with the San Francisco 49ers.
