The Colts' eleventh game was an AFC duel against the Chargers. They took the lead in the first quarter after QB Peyton Manning made a 4-yard TD pass to TE Jacob Tamme. They had a problem maintaining this lead after kicker Nate Kaeding made a 28-yard field goal, followed by ILB Kevin Burnett returning an interception 29&#160;yards for a touchdown, and then with Kaeding hitting a 33 and a 50-yard field goal. They tried to cut the lead as Manning made a 6-yard TD pass to WR Blair White, but the Chargers controlled the second half with Kaeding getting a 30-yard field goal, which was shortly followed by FS Eric Weddle returning an interception 41&#160;yards for a touchdown, then with FB Mike Tolbert getting a 3-yard TD run, and Kaeding making a 20-yard field goal, settling both records to 6-5.  The Colts would have their 5- win season since 2002 at this point.
