Case Keenum started at quarterback versus Baltimore. He completed a 35-yard pass to Andre Johnson on the first play of the game.
The third-year pro signed with the Texans on Monday morning.
Keenum and Thad Lewis are the only quarterbacks on the 53-man roster, and Lewis joined the squad in late November. Lewis has been inactive for the three games he's been a Texan.
Keenum, meanwhile, started eight games in 2013 for Houston. He threw for 1,760 yards, with nine touchdowns and five interceptions. He also was with the Texans during OTAs, minicamp and training capm, and saw action in the four preseason games.
