Check out PRO's Inside Video Review for key Week 18 decisions

Week 18 was busy in the Video Review department, as referees around the league considered nine calls in all: Four for penalty kicks, and five for possible red cards. 

Included in the mix? Luciano Acosta's red card in D.C. United's Fourth of July away trip to Dallas, Leandro Gonzalez Pirez's DOGSO penalty in Atlanta United's nightmare against the Chicago Fire, and additional DOGSO questions that came up in the Real Salt Lake-Columbus Crew SC and Orlando City SC-Philadelphia Union matches. PRO's Greg Barkey takes you behind the scenes to show how the calls were made.
