Head coach Bill O'Brien said he's "pretty close" to making a decision as to whether Lewis or Case Keenum will start this coming Sunday against Baltimore, the Texans' official site reports. However, the coach is not ready to divulge which one will start. "I'm going to keep that one close to the vest," O'Brien said Wednesday. O'Brien added that both Lewis and Keenum will prepare to start "right up until game time," suggesting the identity of his start will not be revealed until Sunday.
