Letroy Guion stripped Forte of the ball near midfield on Chicago's next possession. That led to Walsh's 22-yarder that made it a six-point game, but Cutler and the Bears had one more rally in them.
The late theatrics capped a game that featured no shortage of big plays in the early going.
Patterson got this one off to an explosive start with that huge return to start the game, taking advantage of some big holes and sprinting past a lunging Gould on the way to the end zone. The 105-yarder matched the club record set by Percy Harvin last year and was the first kickoff return for a touchdown by a Bears opponent since 2007.
But along with that promising start there was a bitter finish for Minnesota.
NOTES: The Bears honored the 1963 championship team at halftime, two days after star running back Rick Casares died at age 82. "Oh my God, I think when you talk to my fellow teammates over here, what was all right, true and good about professional football was embodied in Rick Casares," former teammate Ed O'Bradovich said. "Nobody loved the game more than him." Casares played 10 seasons in Chicago and ran for 5,675 yards. He was the Bears' all-time leading rusher until Walter Payton surpassed him and currently ranks third. ... Williams now has five interceptions in his career, most by a Vikings defensive lineman.
