BEARS 23, RAVENS 20, OT
At Chicago, in perhaps the longest game in pro football history — counting a nearly 2-hour weather delay — the Bears (6-4) moved into a tie atop the NFC North with Detroit. Robbie Gould kicked a 38-yard field goal in overtime after Justin Tucker tied it for the Ravens (4-6) with a 21-yarder at the end of regulation.
The big delay came after Tucker kicked a 52-yard field goal with 4:51 remaining in the first quarter. Fans were ordered to take cover. Players headed to the locker rooms as heavy rains and winds whipped through Soldier Field. When they emerged the sky was clearing and the sun coming out, but the rain and wind returned in the third quarter, turning the stands into a sea of ponchos.
"It was pretty muddy, windy," Bears tight end Martellus Bennett said. "I feel like I've been fishing all day."
Ray Rice rushed for 131 yards for Baltimore; he had 289 all season.
STEELERS 37, LIONS 27
At Pittsburgh, the Lions (6-4) saw their short-lived sole division lead disappear as Ben Roethlisberger passed for 367 yards and four touchdowns.
Antonio Brown caught seven passes for 147 yards and two scores and Pittsburgh's defense rebounded from allowing 27 points in the second period. The Steelers kept the Lions (6-4) winless in Pittsburgh for 58 years.
Matthew Stafford threw for 362 yards with two touchdowns and an interception to become the Lions' all-time leading passer. Calvin Johnson hauled in six passes for 179 yards and both scores, but Detroit's two stars disappeared over the final 30 minutes.
SAINTS 23, 49ERS 20
At New Orleans, the 49ers fell far behind in the NFC West race and New Orleans (8-2) took a big step toward an NFC South title and a postseason first-round bye.
Marques Colston capped a record-setting day with a 20-yard reception to get the Saints into field goal range, and Garrett Hartley kicked a 31-yarder as time expired. Hartley, who missed four field goals in the Saints' previous three games, made all three of his field goal attempts in the fourth quarter.
Colston finished with five catches for 80 yards to become the Saints' all-time leader in yards receiving with 7,923, passing Eric Martin's two-decade-old mark of 7,854.
The Saints overcame three turnovers and a failed fourth-down conversion.
Colin Kaepernick completed 17 of 31 passes for only 127 yards and was sacked three times as the Niners (6-4) slipped 3½ games behind Seattle in the West.
