The Texans (12-2) grabbed their first AFC South title last season after the Colts nosedived without injured quarterback Peyton Manning. Manning is gone and Andrew Luck couldn't do much against the inspired Houston defense.
The Colts (9-5) had won three straight and needed a win to clinch a playoff berth a year after going 2-14.
But Houston held them off, thanks in part to three sacks from J.J. Watt, to get back on track a week after an embarrassing 42-14 loss to the New England Patriots on national television. The Texans will have home-field advantage throughout the AFC playoffs in they win out.
