It’ll be a backup battle in Lambeau Field, as Lamar Jackson is officially inactive due to a back contusion.

That means Tyler Huntley will start for the Ravens against Packers backup quarterback Malik Willis, who is stepping in for Jordan Love, who didn’t clear concussion protocol.

Jackson spent the week in treatment trying to get his back to loosen up, but it didn’t do so enough for him to play on “Saturday Night Football” in a must-win for the Ravens. A loss or a Steelers win on Sunday would eliminate the Ravens from playoff contention.

It marks the fourth game Jackson will miss this season, as he was also sidelined for three due to a hamstring injury.

Huntley will get his second start of the season and has played well in his previous appearances.. He completed nine of his 10 passes last week and helped the Ravens beat the Chicago Bears in Week 8, which stands as arguably Baltimore’s best win.

It will be Willis’ sixth start of his four-year career. He also played well last week against the Bears after stepping in for Love, throwing for 121 yards and a touchdown.

The Ravens’ other inactives against the Packers are as follows:
