Input (English): Passage: The 2-1 Lions returned home in Week 4 to face the 3-0 Chicago Bears. Robbie Gould started the scoring for the Bears with a 34-yard field goal, but field goals of 23 and 31 yards by David Akers put the Lions up 6-3. Early in the second quarter, Matt Fort&#233; exploded for a 53-yard touchdown run to put Chicago back up, 10-6. The lead was narrowed to 10-9 when Akers connected on a 41-yard field goal. The Lions then reeled off three straight touchdowns in the span of three and a half minutes. Set up by a 57-yard punt return from Micheal Spurlock, Matthew Stafford scored first when he recovered his own fumble in the end zone following a 1-yard quarterback sneak. On Chicago's next possession, Jay Cutler's second interception of the day was returned by Glover Quin 42 yards, to the Bears 2. One play later, Stafford hit Calvin Johnson in the corner of the end zone for a 2-yard TD. On the Lions next possession, Reggie Bush scored on a 37-yard TD run, hurdling Bears safety Major Wright on his way to the end zone. Robbie Gould closed the half with a 28-yard field goal that made the score 30-13. Gould would connect again on a 25-yarder in the third quarter to get the Bears within two touchdowns. On Chicago's next possession, Ndamukong Suh forced a Jay Cutler fumble, then Nick Fairley scooped up the ball and took it the remaining 4 yards for the score to give Detroit a 37-16 lead. David Akers extended it to 40-16 on a 43-yard field goal in the fourth quarter. The Bears attempted a furious rally in the final minutes.  Cutler hit Alshon Jeffery on a 14-yard TD pass with four minutes left, then connected with Jeffery again for a 2-point conversion to make the score 40-24. On a potential clock-killing drive, Lions running back Joique Bell lost a fumble, and the Bears took advantage with another Cutler TD pass - this one going 10 yards to Earl Bennett. After another successful 2-point conversion, Chicago was within one score, 40-32. But Detroit's Kris Durham recovered the ensuing onside kick to preserve the victory. After throwing just one interception in eight previous games against the Lions, Jay Cutler threw three picks in this game, two of them being grabbed by Lions safety Louis Delmas. Reggie Bush rushed 18 times for 139 yards, and had another 34 yards on four receptions.
