The Bears might have scored 10 points in 10 seconds, but that didn't rattle the Ravens offense.
The unit continued its strong play by answering Chicago's pick-six with an impressive drive that returned the lead to Baltimore, 17-10 with 4:09 to go in the second quarter.
The Ravens drove 80 yards in nine plays and 4:30 with a 5-yard touchdown pass to Torrey Smith wrapping it up. Joe Flacco bounced back from his 12th interception of the season - that tied a career high - by going 5-for-5 for 46 yards and a touchdown on the drive. He's 11-for-16 for 101 yards, a touchdown and a pick.
Ray Rice has run nine times for 67 yards and a score.
Update: Nearly 3 1/2 hours after this game began, halftime has finally arrived with the Ravens leading the Bears 17-13.
Chicago ended the second quarter with a 46-yard field goal by Robbie Gould, giving the Bears 10 points off Flacco's interceptions.
Flacco was picked off twice, giving him a career-high 13 on the season with six games still remaining.
After the game was suspended for almost two hours because of dangerous weather conditions, the Ravens have been outscored 13-7. Haven't we seen this before?
There really is little for the team with the advantage to gain from a delay like that. The Ravens were cruising on both sides of the ball and the Bears were given plenty of time to regroup and come back a different team. Flacco's mistakes have let Chicago get back in this one and he'll need to clean that up in the second half.
The Ravens are doing a good job running the ball with Rice gaining a team-high 70 on the ground so far. Baltimore needs one more yard for its second 100-yard running game of the season. Overall, the Ravens are outgaining the Bears 188-142.
The delay does give the Ravens the minor benefit of knowing how their division foes fared already today. The first-place Bengals beat the Browns to improve to 7-4 while the Steelers won to improve to 4-6. Baltimore will be alone in second place at 5-5 if it can hold on today, keeping the squad 1 1/2 games out of first.
Update II: The most noticeable player in the third quarter was the weather. A pretty uneventful stanza sends this contest to the fourth quarter with the Ravens still leading the Bears 17-13.
The swirling wind forced Baltimore to go for it on fourth-and-8 rather than kick a field goal from the Chicago 32 early in the second half. But that was pretty much it.
A couple of punts, the Ravens turning it over on downs and on to the fourth.
Update III: After not throwing a pass in the third quarter, Josh McCown led the Bears to their first lead on the longest touchdown drive against the Ravens this season.
McCown went 5-for-6 for 68 yards and a score to lead an 11-play, 83-yard drive that chewed 5:59 off the clock. McCown connected with Matt Forte for a 14-yard catch-and-run touchdown pass that gave Chicago a 20-17 advantage with 10:28 to go.
The Ravens haven't been able to get much going since the first drive of the second half. Can they change that now that they need to?
Update IV: The Ravens drove 81 yards in 15 plays, made it all the way to the Bears' 2 and couldn't punch the ball in the end zone. But they did tie things up at 20-20 on Justin Tucker's 21-yard field goal with three seconds to go.
So for the second straight week, Baltimore is headed to overtime with another much-needed win on the line.
Update V: It was close, but Gould converted an overtime game-winning 38-yard field goal to give the Bears a 23-20 victory.
The Ravens punted on their lone possession overtime and had the Bears down to a third-and-9. But McCown completed a 14-yard pass to Alshon Jeffery for first down and then converted a 43-yard pass to Martellus Bennett to put Chicago in field goal range.
Three plays later, Gould beat the wind and put down the Ravens, who couldn't build on last week's win over the Bengals.
Baltimore has now lost four of five and five of seven to slip to 4-6 and into a three-way tie with the Steelers and Browns. The Ravens now trail the Bengals by 2 1/2 games for first place in the AFC North.
