The Cincinnati defense kept the Colts out of the end zone in Thursday's preseason finale at Indianapolis, and that wasn't the end of the good news for the visitors.
Bengals quarterback A.J. McCarron impressed again Thursday night; he just couldn't get into the end zone.
Undrafted rookie kicker Tom Obarski scored, though.
Obarski converted a 28-yard field goal with 2:49 left in the game, allowing the Bengals to edge the Colts. Mike Nugent hit a pair of first-half field goals.
"I thought the poise element (was good)," Bengals coach Marvin Lewis said when asked about the former Alabama quarterback. "The protection isn't always what we want and yet he's always standing poise through it. I like his demeanor on the field and I'm very pleased with that. We're very comfortable with where he is right now."
But probably not comfortable enough to give McCarron the starting job ahead of Andy Dalton, who has taken the Bengals to the playoffs four straight times.
McCarron finished 15 of 28 with 219 yards and was sacked four times.
The game also was marred by three fan injuries at halftime. Lucas Oil Stadium officials issued a statement after the game saying that two men and a woman were hit by a bolt that fell from the roof into the lower seating bowl. One man and one woman were taken to a nearby hospital for further evaluation. Another man was treated at the stadium and released.
None of the injuries were deemed to be life-threatening, Barney Levengood, executive director of the Capital Improvement Board of Managers, said in the statement.
On the field, it was a predictably dull battle of the backups with field goals, punts and turnovers ruling the day.
All the Bengals could muster in the first half were two field goals from Mike Nugent to take a 6-0 lead.
Indy drove inside the Bengals 10-yard line three times in the second half, but got two short field goals from Adam Vinatieri.
And late in the game, rookie quarterback Bryan Bennett, Indy's third stringer, lost a fumble at his 34-yard line, setting up Obarski for the winner.
"I thought our defense played well," Indy coach Chuck Pagano said.
Dalton wasn't the only one sitting out. Andrew Luck missed the game, too. So did Pro Bowl receivers A.J. Green, T.Y. Hilton and Andre Johnson as well as running backs Frank Gore, Jeremy Hill and Giovani Bernard. Colts outside linebacker Robert Mathis, the 2013 NFL sacks champ, also was out, too, even though he was activated from the physically unable to perform list Aug. 25.
Ballard, who missed most of Indy's past two seasons and most of this preseason with injuries, and Peerman each had nine touches in the first quarter.
Ballard finished with nine carries for 29 yards and three receptions for 12 yards before hurting his right hamstring injury in the second quarter. Cincinnati's Peerman had seven carries for 12 yards and three catches for 38 yards.
