The Texans came into Lucas Oil looking to make history by beating the Colts for the first time on their home field. The Texans scored first after K. Lewis intercepted a pass to return it 27 yards for a touchdown. The Colts scored 14 unanswered points in the 2nd quarter to give them a halftime lead of 14-7. Ryan Fitzpatrick was injured in the 3rd quarter, with 3rd string quarterback Tom Savage stepping in for what would be his first NFL game. Early in the 4th, the Texans would go for it on 4th and 1, with Foster running 25 yards for a touchdown. However, the play was called back following an offensive holding penalty. Bullock would kick a 53-yard field goal instead to trail 10-14 with 13:45 left to play. The Colts lead 17-10 with 2:15 left to play following a 29-yard field goal. Houston tried to make a comeback, but Savage's pass was intercepted with 1:34 left. Following the loss, the Texans dropped to 7-7 and the Colts clinched the AFC South title.
