Eight years after their last game in Indianapolis (a 29-13 victory), the Bears returned to play the Colts in week five. The 43rd game between the two franchise, the Bears trailed the series 19-23, but won the last two games, recently a 41-21 win in 2012. "An efficient offensive attack", particularly a rushing-based offense like against the Lions, was a key to success against the Colts defense, according to Jeff Joniak; the Colts allowed the second-highest runs of at least four yards with 51.5 percent. He added the offense should punctuate the run with deep passes, as the Colts were the most penalized defense in the NFL with six pass interference and three personal fouls, along with just four turnovers forced resulting in only three total points. Meanwhile, the Bears defense had to attack Colts quarterback Andrew Luck; Indianapolis was allowing a league-high 15 sacks, was ranked 29th in pass protection efficiency, the second-most hurries (35) the highest number of knockdowns (33) allowed, along with 10 combined false start and holding penalties. Joniak added jet lag could play a factor in the game, as the Colts had lost in London the week before and had no bye week. Connor Barth scored the first points of the game when he kicked a 35-yard field goal on the Bears' opening drive. Adam Vinatieri responded with a 54-yard field goal and the Colts took the lead in the second quarter when Luck threw a one-yard touchdown pass to Dwayne Allen. Both teams traded field goals on their next drives before Brian Hoyer threw a 14-yard touchdown pass to Cameron Meredith. With 11 seconds left in the first half, Vinatieri kicked a 26-yard field goal to give Indianapolis the 16-13 lead at halftime. He converted a 41-yard field goal in the third quarter to increase the margin to six points; when Barth tried a 49-yarder on the next series, he missed it wide left, but redeemed himself with a 24-yard kick in the fourth. Hoyer later led the Bears on a 96-yard drive, ending it with a 21-yard touchdown pass to Jordan Howard; the drive was the longest touchdown-scoring series since a 97-yard possession against the Steelers in 2009. Luck responded with a 35-yard touchdown pass to T. Y. Hilton, who beat Jacoby Glenn for the score, followed by Vinatieri's 35-yard field goal after Meredith lost a fumble. Down by six points, Hoyer attempted to rally the Bears on one last drive but missed an open Alshon Jeffery on fourth down, throwing an incomplete pass to Meredith. The Colts ran out the clock to end the game. With the loss, the Bears fell to 1-4, their worst five-week start since they started the 2004 season 1-4. They ended the game with 522 offensive yards, the most since they recorded 542 in a 1989 win against the Lions and the most in a loss since 1940.
