Kai Forbath kicked a 26-yard field goal in the waning seconds, and the Minnesota Vikings beat the Chicago Bears, 20-17, on Monday night. Harrison Smith's interception of Chicago rookie quarterback Mitchell Trubisky with under three minutes to play set up Forbath's game-winning kick for Minnesota (3-2).

Vikings backup quarterback Case Keenum led three second-half scoring drives in place of Sam Bradford, who was sacked four times in the first half before exiting. His gimpy knee wasn't up to the pressure from the Bears defense.

Keenum finished 17 of 21 for 140 yards and a touchdown. Jerick McKinnon added a 58-yard scoring run for Minnesota.

Making his first NFL start, Trubisky finished 12 of 25 for 128 yards with a touchdown for Chicago (1-4). He also fumbled on a sack that led to a field goal.
