Task: Question Answering
Input (English): Passage: The Bears began their 2008 season by recording an upset victory over the Indianapolis Colts at the newly opened Lucas Oil Stadium. The team won the Super Bowl XLI rematch, by a score of 29-13. The Bears offensive attack featured the debut of rookie running back Matt Fort&#233;, becoming the first Bears rookie running back to start a game since Walter Payton in 1975, coincidentally against the Baltimore Colts (Anthony Thomas also started as a running back for the Bears in 2001). Forte carried the ball 23 times for 123 yards, including a 50-yard touchdown run. The Colts and Bears exchanged field goals, and then Joseph Addai was dropped for a safety.  A Robbie Gould 25-yard field goal on the following drive ended the 1st half. Peyton Manning helped the Colts narrow their deficit by throwing a six-yard touchdown pass to Reggie Wayne. Later in the 3rd quarter, Bears cornerback Charles Tillman forced a fumble, which Lance Briggs picked up and returned for a 21-yard touchdown. The Bears defense was able to contain the Colts the rest of the way, including a key fourth down and one yard stop near midfield early in the fourth quarter. The Bears essentially sealed their victory with 8:56 left on a one-yard touchdown run by fullback Jason McKie. After the game, Al Michaels and John Madden awarded Forte with the Sunday Night Football's "Horse Trailer Player of the Game" award. Adewale Ogunleye received the NFC Defensive Player of the Week award for recording a safety, three tackles-for-loss, and making a key fourth down stop during the game.
