Season-ending injuries to Ryan Fitzpatrick and Ryan Mallett have left the Houston Texans scrambling to find a quarterback ahead of Sunday's game against the Baltimore Ravens.
Fitzpatrick broke his leg Sunday against the Indianapolis Colts and his backup Tom Savage suffered a knee injury that will rule him out of Week 16's contest.
Houston signed Case Keenum on Monday and head coach Bill O'Brien said the team will not announce its starter before Sunday's game.
Keenum will have to duel against Thad Lewis for the starting role.
