The final AFC wild-card position could come down to two AFC South rivals.
The Indianapolis Colts and Houston Texans each earned victories in the early window of Week 13 to create some separation in the standings.
Indianapolis entered Sunday as the No. 7 seed and retained that position with an overtime win over the Tennessee Titans.
Houston defeated the Denver Broncos in a battle of wild-card hopefuls to take over eighth place in the AFC.
The AFC wild-card order could change even more on Sunday depending on what happens with the Cleveland Browns and Pittsburgh Steelers.
