The Houston Texans need a win this weekend against the host Indianapolis Colts ( 10 a.m., CBS) to secure a bye and home-field advantage throughout the AFC playoffs. They also want to build some momentum instead of limping into the postseason despite their 12-3 record. Houston had a chance to secure home-field advantage last week, only to post its worst offensive performance of the season in a 23-6 loss to the Vikings. They now have to win at Indianapolis, where the Texans are 0-10. The Colts, who went 2-14 last season, are 10-5 and have already secured a playoff spot.
