Quarterback Case Keenum was ruled out of Sunday's game with a thumb injury, leading interim coach Wade Phillips to restore Matt Schaub as the starter for the Houston Texans.
Schaub had nine touchdowns and 10 interceptions before he was benched by then-coach Gary Kubiak in favor of Keenum, an undrafted free agent from the University of Houston. Keenum initially sparked the offense but has just one touchdown and five interceptions in the past four games.
Keenum injured the thumb on his right hand last week at Indianapolis but did not miss a snap.
Schaub will be joined in the backfield by Dennis Johnson, who is getting the nod at running back ahead of Ben Tate. Tate was placed on injured reserve with four broken ribs.
Tate played through the painful injury for the past six weeks, since replacing Pro Bowl starter Arian Foster. Foster was placed on injured reserve with a back injury in November.
Johnson has 37 carries for 154 yards this season.
