Unfortunately this is not far from the truth 

 The Dallas Cowboys early morning football practice was delayed on 
Monday for nearly two hours at the Cowboys practice facility.   

 One of the players, while on his way to the field happened to look 
down and notice a suspicious looking, unknown white powdery 
substance on the practice field. 

 The head coach immediately suspended practice while the Texas 
Bureau of Investigation & FBI were called in to investigate.   

 After a complete field analysis, the FBI determined that the white
substance unknown to the players was the goal line.   

 Practice was resumed when FBI Special Agents decided that the 
team would not be likely to encounter the substance again.
