The Bears broke it open late in the second half.
Bush scored from the 1 and holder Adam Podlesh ran in for a 2-point conversion that made it 18-3.
Ponder got picked off by Conte and he returned it 35 yards to the Minnesota 13. That led to a scoring strike from Cutler to a lunging Matt Spaeth on the next play.
NOTES: Vikings coach Leslie Frazier said he and Peterson were going to have a talk about punctuality after Sunday’s delayed arrival. ‘‘There is something that Adrian and I need to talk about regarding getting to the stadium,’’ he said. ... Allen thought his hit on Louis after Winfield’s interception was a clean one. ‘‘I turned around, he was running to make a tackle and I threw myself into him to make a block. My condolences to him and his family. I never, ever, try and intentionally hurt anybody.’’
