In a game delayed nearly two hours by severe weather, Robbie Gould's 38-yard field goal gave the Chicago Bears a 23-20 overtime victory over the Baltimore Ravens on Sunday at rain-soaked Soldier Field.

The Bears improved to 6-4 and moved into a first-place tie with Detroit in the NFC North.

The Ravens got the ball first in overtime but were forced to punt, setting the Bears up at their own 21. On a key third-and-9, Josh McCown hit tight end Martellus Bennett for a 43-yard gain to put the Bears in scoring position.

Subbing for the injured Jay Cutler, McCown hit 19 of 31 passes for 216 yards, a touchdown and no interceptions. Alshon Jeffery had a game-high seven receptions for 83 yards.

Ravens kicker Justin Tucker's 21-yard field goal with three seconds remaining forced the extra period, a full 5:01 since the opening kickoff.

The game was temporarily suspended due to severe weather late in the first quarter and resumed at 2:25 p.m.

Matt Forte (18 carries for 83 yards, 5 catches for 42 yards) took a pass from McCown and galloped 14 yards for a touchdown to put the Bears ahead 20-17 with 10:33 left in regulation.

Gould kicked a 46-yard field goal as time expired in the first half to pull the Bears to within 17-13. That remained the score entering the final quarter, as weather conditions took their toll on the offenses.

Joe Flacco's 5-yard TD pass to Torrey Smith gave the Ravens a 17-10 lead with 4:30 left before halftime. The drive covered 80 yards in nine plays and featured a questionable roughness penalty for a Julius Peppers hit on a sliding Flacco.

Bears rookie defensive end David Bass intercepted a Flacco pass and returned it 24 yards for a touchdown to tie the game at 10-10 with 8:38 to play in the second quarter.

Gould's 20-yard field goal had cut the Ravens' lead to 10-3 with 8:50 left before halftime.

Fans were instructed to clear the stadium seating area and relocate to the nearest covered concourse with 4:51 left in the first quarter and the Ravens leading 10-0. Officials then huddled and decided to suspend play.
