Task: Question Understanding
Input (English): Passage: The Ravens wore their alternate uniforms in the game, hosting cross-conference rivals The Washington Redskins at M&T Bank Stadium. The Ravens scored early following an Ed Reed interception that set up a short touchdown pass from Joe Flacco to Le'Ron McClain. With just under ten minutes to go, Washington ran Clinton Portis up the middle for a first down, but Portis fumbled. Raven Ed Reed recovered the ball and advanced it for a touchdown; the Redskins unsuccessfully challenged, contending Portis was down by contact. Those would be the only points on the board for either team in the first half. In the second half, a long Ravens drive beginning at just under eleven minutes to go in the third quarter set up a 32-yard Matt Stover field goal. The Redskins answered with a drive starting late in the third quarter and ending in the early fourth quarter that set up a 43-yard Shaun Suisham field goal. Receiving the kickoff, Baltimore ran just two plays before surrendering the ball to Washington on a Willis McGahee fumble that led to a short drive capped by a touchdown pass from Jason Campbell to Antwaan Randle El. Another kickoff led to a very long Baltimore drive that consumed most of the remaining time. Ten of twelve plays were runs by Le'Ron McClain. A 28-yard touchdown pass to Derrick Mason capped this drive. With three and a half minutes left, the Redskins next drive ended in an Ed Reed interception that enabled Baltimore to burn most of the remaining time. The Redskins took possession for their final series with 0:16 remaining but could not score.
