During the March 30, 2012, DC United vs. FC Dallas MLS match, there was a play late in the first half where Dallas player Perez (#9) scored after receiving the ball following a deflection/misplay by DC United defender Dudar (#19). At the time the ball was last played by Perez’s teammate Hernandez. who chested the ball forward, Perez was in a clear offside position. All of our training as well as the Advice to Referees states that in order for the offside situation to “reset” the defender must control and play the ball. A deflection, miskick, or misplay is not supposed to reset the offside situation. In this case the AR did not raise his flag for offside and the goal was allowed to stand.
USSF answer (April 4, 2012):
An official review of the situation at the highest levels confirms that the call should have been offside.
