INDIANAPOLIS (AP) — Tom Obarski made a 28-yard field goal with 2:49 left in Thursday night’s preseason finale and the Bengals defense kept Indianapolis out of the end zone for a 9-6 victory.

Cincinnati won for the third time in four weeks, while the Colts, at 1-3, finished with their 12th consecutive non-winning preseason.

The game was marred by a fan who was injured at halftime. Colts chief operating officer Pete Ward said a woman was hit by falling debris when the retractable roof opened. Ward said she walked to a nearby first-aid station.

But with both teams’ biggest stars sitting out, the game was devoid of excitement.

The Bengals took a 6-0 halftime lead on two Mike Nugent field goals.

Indy got inside the Cincinnati 10-yard line three times in the second half, but got only two field goals from Adam Vinatieri — before Obarski won it.
