FC Dallas has become part of the Major League Soccer history books, becoming the first side to have a goal ruled out by video review.
The Hoops were down 3-0 to the Philadelphia Union when Maxi Urruti followed up a Cristian Colman effort and knocked home the rebound, seemingly pulling one back for the away side.
However, Colman's effort included a kick out at Union goalkeeper John McCarthy, and referee Ricardo Salazar was alerted to the possibility of a foul.
After reviewing the footage, Salazar ruled that there was indeed a kick on McCarthy, and that the goal would be disallowed.
