Houston Texans coach Bill O'Brien isn't revealing who will start at quarterback Sunday against the Ravens.
The Texans can go with Case Keenum, who was signed this week off of the St. Louis Rams practice squad and went 0-8 as a starter for the Texans last season, or they can start mobile former Buffalo Bills quarterback Thaddeus Lewis.
"We're not going to publicly name who's starting," O'Brien said during a conference call with Baltimore reporters Wednesday. "We'll let everybody see that when the game starts."
The Texans don't hold much of an advantage in this situation, but they do have the element of surprise. We would guess that Thaddeus Lewis gets the nod since he has been with the team longer, but Case Keenum had some success with Andre Johnson in 2013 and knows the offense well.
