Lamar Jackson‘s return timetable looks set to be pushed back another week. John Harbaugh said Friday it is a “fair assumption” Tyler Huntley will start against the Steelers.

This will be Huntley’s fourth start this season and ninth over the past two. Jackson’s initial timetable did not indicate he could miss four games, but it appears the Ravens will now hope for a Week 18 return. Jackson has not practiced since suffering a PCL sprain nearly a month ago. The Steelers will be set to face Huntley twice this season; the Ravens won the teams’ first matchup.
