Lewis was placed on injured reserve with the designation to return after he tore his triceps on Oct. 14 in Baltimore's victory over the Dallas Cowboys. Lewis is eligible to return to the practice field this Thursday. If Lewis is able to do so, the first game he will be able to participate in will be the against the Broncos.
Lewis has tried to speed up the recovery process with the use of a hyperbaric chamber and is undergoing platelet-rich plasma therapy, which theoretically helps improve healing and promote tissue growth.
The Ravens defense has been struggling without Lewis in the middle, as they are ranked 24th in the NFL in total yards allowed, but the team has been able to overcome that and win their last four games without Lewis in the lineup.
