HOUSTON (AP) - The Houston Texans clinched the AFC South with a 29-17 win over the Colts to help erase the memory of a blowout loss to New England.

Coach Gary Kubiak still sees plenty of room for improvement after Sunday's game and is challenging his team to play better with gaining home-field advantage throughout the AFC playoffs still within reach.

San Francisco's win over New England on Sunday night left the Texans needing just one win in their last two games to secure home-field advantage.

One of Kubiak's biggest concerns is Houston's inability to finish drives lately. Houston was just one of five on red zone opportunities on Sunday.

They scored their only offensive touchdown on their second drive, and settled for field goals the rest of the way.
