Lamar Jackson won't play in Sunday's playoff game at the Cincinnati Bengals as his left knee "remains unstable."

Jackson indicated on Twitter that he has "suffered a PCL Grade 2 sprain, on the borderline of a strain 3."

"There is still inflammation surrounding my knee and my knee remains unstable," Jackson wrote. "I wish I could be out there with my guys more than anything, but I can't give a 100% of myself to my guys and fans. I'm still hopeful we have a chance."

The Baltimore Ravens will start either Tyler Huntley or Anthony Brown in the game.

The Ravens initially described his return as "week to week," but he hasn't suited up for the past 39 days and, as of last week, was still walking with a limp.
