Any of three answers is acceptable. Brock Osweiler in January 2017 became the fourth quarterback to start a playoff game for the Houston Texans. The first was a 2011 fifth-rounder from the University of North Carolina, who signed with the Bills in 2017 but suffered a concussion in a pre-season game. The second holds several Texans franchise records including games played at quarterback and career passing yards. The third was an undrafted free agent from Michigan State, who in 2017 started (and lost) six games before being benched (for rookie C.J. Beathard) by a team that recently released him. Name any one of those three quarterbacks.
T.J. Yates, Matt Schaub, or Brian Hoyer
