With the Broncos clinging to a six-point lead with 1:51 remaining, Miller burst past right tackle Joe Reitz and swiped the ball from Luck’s grasp. Fellow linebacker Shane Ray scooped up the ball and returned it 15 yards for a touchdown.

Miller added a sack on the last play as the Broncos (2-0) sent the banged-up Colts limping to their third consecutive 0-2 start.

They did it by rattling Luck, who started 5 for 18 before he engineered a couple of second-half touchdown drives. Luck completed just 21 of 40 passes for 197 yards and was sacked five times.

Trevor Siemian outshone Luck, just as he did Cam Newton in the opener. He completed 22 of 33 passes for 266 yards.

Cornerback Aqib Talib returned an interception 46 yards for a touchdown early in the fourth quarter, giving Denver a 23-13 lead.

Talib stepped in front of wide receiver Phillip Dorsett to snag Luck’s pass, which he returned through traffic down Denver’s jubilant sideline. His ninth career pick-6 was his fifth for Denver, a franchise record.

Luck threw a 7-yard TD pass to Frank Gore with 4:02 remaining, pulling the Colts to 23-20. The drive was kept alive by safety Darian Stewart’s roughing penalty for smacking the quarterback in the helmet as he slid for the first down on a third-and-1 scramble at his own 30.

Stewart was fined 18,231 for a helmet-to-helmet hit on Newton in the opener and can expect another fine this week.

D’Qwell Jackson stuffed C.J. Anderson on third-and-1 from the Colts 17 and Brandon McManus’s 35-yard field goal made it 26-20 with 1:51 left.

After a touchdown, Luck lined up and took the snap.

In a split-second, the ball was on the ground, and Luck watched helplessly as Ray scooped it up and scored.

THIN AIR: One week after Panthers punter Andy Lee had a 76-yard kick in Denver’s mile-high air, Pat McAfee had a 72-yarder for the Colts that was nearly blocked but ended up bouncing into the north end zone for a touchback.

HONORING GREATS: The Broncos unveiled signs in the south end zone before the game honoring the players with retired numbers: Hall of Famers John Elway (7) and Floyd Little (44) and the No. 18 for Frank Tripucka, the first QB in franchise history. Tripucka’s sign included a mention of Peyton Manning . Tripucka, who played from 1960-63, gave his blessing for Manning to wear the number when he was with the Broncos from 2012-15.

INJURY UPDATE:

Colts: CB Antonio Cromartie (shoulder) got hurt when he smacked into Emmanuel Sanders on the game’s second snap, but returned in the second quarter. WR Donte Moncrief left in the second quarter with a head and neck injury. CB Rashaan Melvin left in the third quarter with cramps. RG Denzelle Good left in the fourth quarter with a back injury. Indianapolis began the day without three starters from their secondary in cornerback Vontae Davis (ankle) and Patrick Robinson (concussion) and safety T.J. Green (knee).

Broncos: RT Donald Stephenson went out in the first quarter with a calf injury and was replaced by Darrion Weems. OLB DeMarcus Ware injured his right elbow in the third quarter and didn’t return. He shared a sack with Derek Wolfe.

Novak connected from 32, 24, 31 and 43 yards for the Texans

Cairo Santos made three field goals in the fourth quarter to cut the lead to 19-12, but Houston recovered the onside kick with less than a minute left to seal the victory.

The Texans (2-0) showed that they are a much different team than the one that was embarrassed in a 30-0 wild-card playoff loss to the Chiefs (1-1) in January, when quarterback Brian Hoyer had five turnovers.

New quarterback Brock Osweiler did throw two interceptions but the Chiefs had more trouble taking care of the ball, with Houston’s defense setting a franchise record by recovering three fumbles in the first half.

The first came when a high snap sailed over Alex Smith’s head. J.J. Watt shoved him out of the way with one hand and pounced on it, showing he was getting back to his old self after July back surgery.

Osweiler, who finished with 268 yards passing, connected with Hopkins on a 27-yard touchdown pass on the next play to make it 7-0.

Watt continued to shine later in the first quarter when he took Smith down for his first sack this season, forcing the Chiefs to kick a field goal that made it 7-3.

Houston was leading by seven in the second quarter when Spencer Ware fumbled, Kevin Johnson scooped it up for his first career recovery and returned it 52 yards. The Texans couldn’t get their offense going after that and settled for a 24-yard field goal to make it 13-3.

John Simon forced the last fumble of the half on his strip-sack of Smith. It was recovered by Whitney Mercilus. But once again Houston failed to move the ball and Novak’s try for a 57-yard field goal fell short as time expired in the first half.

Marcus Peters intercepted Osweiler at the goal line on Houston’s first possession and picked him off again late in the third quarter.

That led to a 43-yard field goal that cut the lead to 13-6.

A field goal by both teams after that left the Texans up 16-9.

FULLER FLOURISHES

Houston rookie receiver Will Fuller finished with four receptions for 104 yards to become the first rookie in franchise history with consecutive 100-yard receiving games to start his career. The 21st overall pick in this year’s draft had 107 yards receiving in his NFL debut last week.

INJURY REPORT

Houston rookie WR Braxton Miller injured his hamstring in the first half and did not return.

ELITE COMPANY

Watt finished with 1.5 sacks on Sunday to give him 76 sacks in his 82nd career game. He’s the second fastest in NFL history to reach 75 sacks behind Hall of Famer Reggie White who did it in 65 games.

NO, NO, NO

Peters learned that wagging your finger in the face of an opponent like NBA Hall of Famer Dikembe Mutombo did after blocking a shot is frowned upon on the NFL.

Peters forced an incompletion on a deep ball thrown to Fuller in the second quarter and wagged his finger at him for several seconds. The move earned him a 15-yard penalty for taunting and a warning that a second such penalty would result in an ejection.

SPREADING THE WEALTH

Hopkins and Fuller gave Houston two players with at least 100 yards receiving for the eighth time in franchise history and the first time since 2013.

BRING IT BACK

Kansas City rookie Tyreek Hill had a 105-yard kickoff return for a touchdown negated because of a holding penalty late in the fourth quarter.
