(AP) Matt Forte slipped into the end zone from 5 yards for one touchdown and broke loose for 55 yards to set up another and the Chicago Bears took a 17-0 lead over the Pittsburgh Steelers after the first quarter on Sunday night.
Forte scored four plays after a fumble by Pittsburgh quarterback Ben Roethlisberger.
He then ripped off his longest run of the season to put Chicago in position for a 1-yard fourth-down plunge by Michael Bush as Chicago's bid for a 3-0 start began with a flourish.
The Bears rode a pair of fourth-quarter comebacks to win their first two games and came out throwing to take an early lead.
Working quickly to avoid the myriad of blitzes thrown his way, Cutler completed 8 of 10 passes on a 51-yard opening drive that ended with a 47-yard field goal by Robbie Gould.
Four of those completions went to Alshon Jeffery, who came in with six receptions through the first two weeks.
The Steelers hoped the return of tight end Heath Miller would pump some life into the NFL's 31st-ranked offense. Miller hadn't played since tearing ligaments in his right knee last December against Cincinnati.
He sprinted onto the field on Pittsburgh's opening possession and Roethlisberger found him for a 6-yard gain on the team's second offensive play.
The momentum quickly vanished. Roethlisberger dropped back to pass on Pittsburgh's third offensive snap and stepped up in the pocket to evade the rush.
Chicago linebacker D.J. Williams reached for Roethlisberger's hands and the ball came loose. Anderson pounced on it at the Pittsburgh 17.
Chicago needed four plays to make it 10-0. Cutler found Forte for an 11-yard gain on third-and-9, and one play later Forte flipped into the end zone for his second touchdown of the season.
Pittsburgh went nowhere and punted, giving Chicago the ball near midfield. Forte ran through a gaping hole and darted to the right sideline before being pushed out of bounds at the Pittsburgh 5.
A defensive pass interference call put the ball at the 1. Three plays went nowhere before Bush's second effort on fourth down gave the Bears a commanding lead.
