HOUSTON — Andrew Luck passed for 370 yards and three touchdowns, and T.Y. Hilton finished with a career-high 223 receiving yards as the Indianapolis Colts held on for a 33-28 win over the Houston Texans on Thursday night at NRG Stadium.

Indianapolis (4-2) led 24-0 after the first quarter before Houston (3-3) mounted a comeback.

Luck and Hilton connected on a critical 33-yard touchdown late in the third quarter, a scoring play that supplied the Colts with a 12-point lead following a failed two-point conversion attempt.

The cushion proved vital, especially after Texans defensive end J.J. Watt returned a Luck fumbled snap 45 yards for a touchdown with 10:46 left in the fourth quarter. Watt’s third touchdown of the season pulled Houston within 33-28.

Texans receiver Andre Johnson fumbled in Colts territory with 4:38 to play. Colts cornerback Vontae Davis forced the fumble, and safety Mike Adams recovered.

Houston got one final drive, starting at its 9-yard line with 2:15 remaining, but quarterback Ryan Fitzpatrick was stripped by Colts end Bjoern Werner. Indianapolis linebacker D’Qwell Jackson recovered.

The Colts extended their AFC South winning streak to 10 games while improving to 8-0 on Thursday NFL Network contests, 7-0 on the road.

Texans running back Arian Foster rushed for 109 yards and two touchdowns on 20 carries. Fitzpatrick finished 15-for-23 for 212 yards and a touchdown.

Luck completed 25 of 44 passes, nine of them to Hilton, and was intercepted once.

While the Texans amassed just 2 total yards in the first quarter, the Colts scored to cap each of their four possessions and set the stage for a blowout victory. Kicker Adam Vinatieri closed the first drive with a 27-yard field goal for a 3-0 lead before the Colts caught the Texans napping with an onside kick recovered by punter/kickoff specialist Pat McAfee.

The Colts added three consecutive touchdown marches, the final two ending with Andrew Luck scoring strikes of 5 and 4 yards to running back Ahmad Bradshaw and tight end Coby Fleener. Running back Trent Richardson gave the Colts a 10-0 lead with his 5-yard run one snap after Hilton hauled in a 49-yard pass following the onside kick.

Houston finally showed some life in the second quarter, covering 80 yards in 11 plays as Johnson snagged a 4-yard pass from Fitzpatrick for a touchdown with 9:43 left in the half. Just over one minute later, the Texans cut into that 24-7 deficit when linebacker Justin Tuggle picked off a deflected pass three snaps before Foster dashed 12 yards for a touchdown.

Indianapolis responded with a seven-plus minute drive, exhausting most of the remainder of the second quarter before Vinatieri added a 44-yard field goal that rebuilt the Colts’ lead to 27-14 at intermission.
