After the tough home win over the Vikings, the Colts stayed home for a division rival duel against the Jaguars.  Scoring started early as the Jags drew first blood scoring a 44-yard field goal from Josh Scobee to take a 3-0 lead.  However, the Colts took the lead with Andrew Luck's 40-yard touchdown pass to T. Y. Hilton for a 7-3 lead.  The Colts increased their lead in the 2nd quarter with Andrew Luck's 4-yard touchdown pass to Mewelde Moore for a 14-3 halftime lead.  In the 3rd quarter, the Jaguars were able to fire back as Maurice Jones-Drew ran in a touchdown from 59 yards out to cut the lead to 14-10.  Followed up quickly by Scobee's 47-yard field goal to shorten the lead to a point 14-13.  In the fourth quarter, the Jags were able to take the lead with Scobee kicking a 26-yard field goal for a 16-14 lead.  The Colts however retook the lead with Vinateri's 37-yard field goal for a 17-16 lead.  But then the Jags were able to complete the comeback attempt 11 seconds later with Blaine Gabbert's touchdown pass to Cecil Shorts III (with a failed 2-point conversion) to make the final score 22-17. With the loss, the Colts went into their bye week at 1-2. It would also be their last loss to a division opponent at home until 2015.
