Seven people suffered minor injuries when a runaway electric cart raced unmanned from an end zone to midfield and plowed into them after a high school football playoff game in Texas. The incident happened after Spring Dekaney beat Cibolo Steele, 34-14, to win the Texas 5A Division II football title at Cowboys Stadium in Arlington on Saturday night. Of the seven treated for minor injuries at the stadium, one man with leg abrasions was taken to a nearby hospital for a precautionary examination, Arlington Fire Lt. Darrel Whitfield said Sunday.
