INDIANAPOLIS —The Indianapolis Colts (1-3) fell to the Houston Texans (1-3), 37-34, today in their AFC South Division matchup at Lucas Oil Stadium. Here are updates from today's game:

OVERTIME

— J.J. Watt doesn't realize tails never fails; calls heads, and the Colts win the overtime coin toss and take the ball.

— The Colts go on a 13-play, 50-yard initial drive in overtime, which ends with a 44-yard Adam Vinatieri field goal, his second of the day. Indy leads 34-31 with six minutes left in the OT period, and the Texans get an opportunity to match or win with a touchdown.

FOURTH QUARTER

— Eric Ebron with his third TD grab of the season, this time from five yards out. The Texans' defense wasn't set, and was scrambling to cover the tight end on the left side, and Andrew Luck immediately launched a pass his way. The two-point attempt fails, though, but the Colts cut the Texans' lead to five, 28-23, with 7:41 left in the fourth quarter.

— Colts tie this thing up at 31. A nine-play, 85-yard drive that took 2:13 off the clock results in a nine-yard touchdown pass from Luck to running back Nyheim Hines, his second touchdown grab of the day. A two-point conversion pass to Chester Rogers is good. Great comeback effort here.

THIRD QUARTER

— Injury update: CB Kenny Moore has a concussion and he is out.

— Deshaun Watson runs it in from five yards out, and the Texans now lead 28-10 with 6:39 left in the third quarter. It was a 15-play (plus one penalty), 79-yard drive that took an excruciating 8:21 off the clock.

— The Colts finally get some life. Andrew Luck finds rookie running back Nyheim Hines, all 5-foot-9 of him, who beats safety Tyrann Mathieu in one-on-one coverage to go up and high point a 14-yard touchdown catch. It's Hines' first-career touchdown reception, and his second touchdown overall. Texans' lead cut to 28-17 with 5:14 left in the third quarter.

— Watson picked off. Pierre Desir with his second-career interception, as he stole the ball from DeAndre Hopkins. Momentum now clearly in the Colts' favor. Indy offense takes of at the Houston 45, down 11.

— At the end of the third quarter, the Texans lead the Colts, 28-17.

SECOND QUARTER

— Adam Vinatieri makes history, connecting on a 42-yard field goal with two seconds remaining in the second quarter to cut the Texans' lead to 21-10. Vinatieri moves into sole possession of first place in NFL history in made field goals with 566.

— Halftime: Texans lead the Colts, 21-10.

FIRST QUARTER

—Marcus Johnson logs his first reception for the Colts on the opening possession. It's a 16-yard pickup on 3rd and 11. First down. On the very next play, Andrew Luck finds T.Y. Hilton, who slips away from the Houston defenders for 40 yards, but then he goes down and appears to be in pain. We'll get an update as soon as one is provided.

— Touchdown, Colts. Luck completes all five of his passes on their opening drive for 68 yards, and connects with Zach Pascal for a four-yard touchdown. Indy takes an early 7-0 lead over the Texans with 11:17 left in the first quarter.

— After a superb opening drive by the Colts' defense — Denico Autry and Darius Leonard logging back-to-back sacks — the Colts were pinned back to their own 2-yard line to start their second drive. But on the second play, there was a botched snap from center Ryan Kelly in the end zone, and Texans defensive end Jadeveon Clowney fell on it for the defensive touchdown. Colts, Texans tied at 7 with 5:19 left in the first quarter.

— Injury update: Hilton (chest) is questionable to return.
