Football practice was delayed on Monday for nearly two hours for the Cronulla Sharks. 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. The Coach immediately suspended practice while the Police were called in to investigate. After a complete field analysis, the Police determined that the white substance, unknown to the Sharks players, was the goal line. Practice was resumed when the Police decided that the team would not be likely to encounter the substance again.
