Oakland Raiders football practice was delayed on Monday for nearly two hours. One of the players, while on his way to the locker room, happened to look down and notice a suspicious-looking, unknown white powdery substance on the practice field.

Practice was immediately suspended while the Drug Enforcement Agency was called in to investigate.

After a complete field analysis, the DEA determined that the white substance unknown to the players was the goal line. Practice was resumed when the DEA agents decided that the team would not be likely to encounter the substance again.
