The gospel truth, even as SI was still working on the issue, Lewis took a knee to the back in a game against the Bengals, but didn't miss a play. He missed every day of practice the next week, however, and became the first Ravens defensive starter to miss a game this season when he didn't suit up against Tennessee. Four days later he had surgery to have a pocket of blood drained from his swollen back and was listed as questionable for the next game.
