Lewis missed this past Sunday's game against the Bengals with a toe injury, snapping his consecutive games played streak at 57. He hadn't missed a game since the 2007 season.
"I am doing everything in my power to get back as fast as I can, whether that's this week, next week or whenever it is, I am doing everything I can to be out there with my team," Lewis said in a statement on Tuesday. "I want to play Thursday night, and I am making some progress."
Lewis missed practice all last week, but was a limited participant this week.
The Ravens signed linebacker Josh Bynes to the active roster on Wednesday.
