INDIANAPOLIS – This one had a decidedly one-sided feel.

And while the one side that was good for the Jaguars on Sunday was very, very good – for a half, anyway – the struggles were far too real on the other side.

The Jaguars forced three turnovers, and the defense harassed quarterback Andrew Luck in the first half. That kept the game close early, but with the offense struggling mightily throughout the Jaguars loss to the Indianapolis Colts, 23-3, on Sunday afternoon.

The AFC South-leading Colts improved to 7-4 in front of 64,328 at Lucas Oil Stadium, pulling away from a three-point halftime lead with touchdowns on their first two drives of the third quarter.

The Jaguars (1-10) lost a fourth consecutive game.

Trent Richardson's 1-yard touchdown run with 8:31 remaining in the third quarter gave the Colts a 13-3 lead, and Luck passed 73 yards to wide receiver T.Y. Hilton on the ensuing possession pushed the lead to 20-3.

The Colts held a 273-90 advantage in total yards at that point.

The Jaguars finished with just 194 total yards, including 88 in the second half. The Jaguars had minus-12 yards in the third quarter as the Colts pulled away.

Luck, who entered the game with 28 touchdown passes and 10 interceptions, threw for just 112 yards and no touchdowns in the first half while being sacked five times. He finished the game completing 21 of 32 passes for 253 yards with a touchdown and no interceptions. Hilton caught four passes for 122 yards and a touchdown.

The Colts rushed for 175 yards.

Jaguars quarterback Blake Bortles had one of his most difficult games of the season, completing 15 of 27 passes for 146 yards and no touchdowns with an interception.

Defensive end Chris Clemons had three sacks for the Jaguars, all in the first quarter. The Jaguars had five sacks in the first half and none in the second half.

The Jaguars, who lost to the Colts 44-17 in a Week 3 game in Jacksonville after trailing 30-0 at halftime, pressured Indianapolis throughout the first half, creating havoc, sacking Luck five times and forcing three turnovers.

The Jaguars also forced five fumbles in the first half, with Clemons and the defense setting the tone and giving the Jaguars a very real chance at that point.

Clemons' first sack forced a fumble that gave the Jaguars possession, but Colts cornerback Vontae Davis intercepted Bortles two plays later and returned it to the Jaguars 21. Colts kicker Adam Vinatieri converted the first of three field goals on the ensuing possession to make it, 3-0.

A 28-yard field goal by Josh Scobee with 4:17 remaining in the first quarter made it, 3-3, and Vinatieri converted a 20-yarder with 12 seconds remaining in the half to give Indianapolis a three-point halftime lead.

The Colts' two third-quarter touchdowns pushed the lead to 17, and Vinatieri converted a 32-yard field goal early in the fourth quarter to make it 23-3.

TURNING POINT

This actually came in the first half. Though the Jaguars forced five fumbles and three turnovers, the Colts still led 6-3 at halftime because the Jaguars managed just five first downs and 104 total yards. The Jaguars had 34 yards passing at halftime. The Colts then scored on their first drive of the second half, with Richardson's one-yard touchdown run with 8:31 remaining in the second quarter giving Indianapolis a 13-3 lead.
