INDIANAPOLIS—Offensively, it was drops by a handful of players.
Defensively, it was mental mistakes that kept four separate double-digit play San Diego drives moving deeper into Colts territory.
Add it all up and the Colts (4-2) fell 19-9 to the San Diego Chargers (3-3) on Monday Night Football.
Areas in which the Colts have dominated all season long (third-down conversions and time of possession) were nowhere to be found on Monday night.
San Diego controlled the ball (38:32-21:29) and converted 7-of-14 third-downs compared to just a two-of-10 effort from the Colts.
Chargers kicker Nick Novak booted four field goals. Rookie wide receiver Keenan Allen caught a career-high nine passes for 107 yards and a touchdown to make up the scoring for the home team.
A 50-yard field goal by Adam Vinatieri at the halftime gun brought the Colts to within four points at 10-6.
The Chargers would once again eat up a majority of the third quarter clock and took a 13-6 lead into the final stanza.
Heading into a quarter the Colts had played their best football in all season long; the final stanza did not follow the same script as past weeks for Indianapolis.
After the two teams traded field goals, the Colts got the ball back up against their own goal with just over four minutes remaining.
However, a three-and-out would follow and Novak connected on a 50-yard field goal with 1:55 remaining to make up the final score of 19-9.
As the clock ticked away on Monday night, ESPN showed a graphic that pretty much summed up a night that was "uncharacteristic" to what the Colts had previously done in 2013.
There was the time of possession, third-down conversions, dropped passes and penalties (three Colts penalties into Chargers first downs) that told the story.
It's mistakes the Colts hope are just an anomaly with the undefeated Denver Broncos coming to Lucas Oil Stadium for Sunday Night Football in just six days.
FIRST QUARTER (11:27 remaining)
The Colts took the opening kickoff and marched down the field before ending the drive with a 30-yard Adam Vinatieri field goal.

FOURTH QUARTER (7:21 remaining)
With an up-tempo offense, the Colts offense moved quickly across the 50-yard line but had to settle for a 51-yard field goal by Vinatieri.
