In week six, the Bears traveled to M&T Bank Stadium to play the 3-2 Baltimore Ravens, whom the Bears led 3-2 in five all-time meetings. The series had been a see-saw in victors, with the winning team alternating each time; the Bears won the most recent game in 2013 23-20, but the Ravens won the latest game in Baltimore (a 31-7 rout in 2009). For the Bears offense, the unit hoped to provide more support for Mitchell Trubisky in his first NFL away game. "The kid's going to be special and we've got to do our jobs around him; keep getting in the right spot, make plays and catch the football, and making sure we're keeping him out of first-and-17s," offensive coordinator Dowell Loggains stated. "We have a lot of faith and confidence in Mitchell." To do this, USA Today's Lorin Cox wrote the offensive line needed to stop Ravens nose tackle Michael Pierce, whose 13 stops in 2017 tied for fifth among defensive linemen. On defense, the Bears entered the game with the sixth-ranked defense (allowing 305 yards per game) that also ranked ninth in average yards allowed per play (5.07). With Danny Trevathan returning from suspension, the defense faced a Ravens offense that ranked sixth in rushing with 130.4 yards per game. On the other hand, Baltimore's offensive line - particularly the guards - had been struggling due to injuries, and Cox wrote the defense should take advantage of the openings. While the Bears had yet to record an interception in 2017, Ravens quarterback Joe Flacco had thrown 33 in his last 31 games, including one in ten consecutive games; Cox added, "It's up to this defense to actually finish the turnover." The first five drives of the game ended with punts. The Bears opted for a run-based attack for much of the game; on their first scoring drive in the second quarter, all but one play was a run, with the series ending on Connor Barth's 24-yard field goal. On the Ravens' next drive, Maxx Williams was stripped by Christian Jones and Trevathan recovered the loose ball. Although the Bears were unable to capitalize on the takeaway, the defense recorded another turnover on the next drive when Bryce Callahan intercepted Flacco's pass intended for Breshad Perriman. On a halfback option, Tarik Cohen eventually threw a 21-yard touchdown pass to Zach Miller to put the Bears up 10-0. Justin Tucker kicked a 27-yard field goal to put the Ravens on the scoreboard with three seconds remaining in the first half. During the third quarter, Trubisky led a 66-yard drive that ended with a 27-yard touchdown pass to Dion Sims. During the ensuing kickoff, Joshua Bellamy appeared to trip Ravens kick returner Bobby Rainey, but Rainey instead got back up and ran 96 yards for a touchdown. Upon review, the referees determined Bellamy's hand did not touch Rainey. Subsequently, the Bears committed two turnovers: Cohen fumbled at the Bears' 39-yard line - which set up Tucker's 31-yard field goal to narrow the gap to four points - and Trubisky was strip-sacked by Lardarius Webb with C. J. Mosley recovering. The Ravens reached the Bears' 30-yard line, where Flacco was intercepted by Adrian Amos, who returned his first career interception 90 yards for the touchdown to put the Bears up by 11 points with 5:08 left in the game. However, Tucker kicked a 50-yard field goal with 2:53 remaining, while Michael Campanaro scored on a 77-yard punt return touchdown and Flacco completed the two-point conversion to Nick Boyle to tie the game at 24 apiece and enter overtime. Neither team was able to score on their first drive; on Chicago's second series, the offense was pinned at its own seven-yard line. Jordan Howard recorded a 53-yard run on the first play of the possession, which was later followed by Trubisky's 18-yard pass to Kendall Wright on third down to draw the Bears closer. Barth kicked a 40-yard field goal to win the game. It was the Bears' first road victory since 2015 against the Buccaneers, breaking a ten-game losing streak. The Bears' rushing attack resulted in a career high 167 rushing yards on 36 carries for Howard, while Cohen had 14 carries for 32 yards. Trubisky threw just 16 passes, completing eight for 113 yards and a touchdown. John Fox explained the Ravens were the reason for the run-based strategy, having used the same philosophy with the 2012 Denver Broncos; in that team's game against Baltimore, the Broncos ran 44 times against just 21 passing plays despite the presence of Peyton Manning.
