An escalator malfunctioned and injured seven people at Giants Stadium last night, shortly after the Giants lost to the undefeated Patriots, 38-35, in the final game of the regular season. One of the injured fans appeared to have a fractured leg, while others had scrapes and bruises, said Jim Minisch, executive vice president of facilities for the New Jersey Sports and Exposition Authority. Two other two fans were apparently more seriously injured, but Minish did not have further details on their condition. The seven people were taken to Hackensack University Medical Center, where they were still being treated today. Hospital spokeswoman Nancy Radwin would not reveal any details regarding the injuries. "I can confirm that there are multiple victims,'' she said. The escalator at Gate A apparently failed at the bottom steps, state police Lt. Jim Crann said. The escalator runs from the stadium's upper tier to the ground level, and Crann said it appeared that some bottom steps became bent, causing some fans to sustain foot and leg injuries. According to Minisch, the incident happened about 10 minutes after the game ended. He said there was no immediate explanation why the problem occurred. The elevator will be closed for today's game between the Jets and Chiefs.
