INDIANAPOLIS — Arian Foster's 13-yard run up the middle on the Texans' opening drive of the third quarter narrowed the margin to 14-13. A 37-yard field goal from Graham with 5:22 remaining in the third quarter gave Houston its only lead of the day at 16-14.
On the ensuing kickoff, former Southern Illinois running back Deji Karim gave the Colts a desperately needed lift, taking Graham's kickoff back 101 yards for the eventual go-ahead touchdown. Karim has sparkled as a kickoff returner since rejoining the team on Dec. 11.
The return was the first by an Indianapolis player since former linebacker Tyjuan Hagler went 41 yards for a TD against Jacksonville on Dec. 19, 2010. It was also the longest kickoff return for a touchdown by an Indianapolis player and the fourth longest in franchise history.
Rookie wide receiver T.Y. Hilton closed out scoring for the Colts, hauling in a 70-yard TD pass from Luck with 11:27 left in the game. It was Hilton's seventh receiving touchdown of the season and a league-leading fifth coming on throws that were more than 20 yards downfield.
What made the play stand out was the fact that Indianapolis was facing a 3rd-and-23 situation after consecutive runs by Ballard netted a loss of three yards and a holding penalty on offensive tackle Anthony Castonzo nullified a 24-yard pass play to wide receiver Reggie Wayne.
Houston had one more opportunity to cut into the Colts' lead, but Indianapolis' defense held firm. The Texans managed to picked up a pair of first downs on throws from quarterback Matt Schaub to wide receiver Kevin Walter (15 yards) and Foster (18 yards).
Schaub's fifth pass attempt of the drive was overthrown to wide receiver Andre Johnson and intercepted by cornerback Vontae Davis, his second of the game and third in the past two weeks.
