Philadelphia Union striker Cory Burke dribbled hard into the 18-yard box, slammed on the brakes, cut sharply to his right, got half a step on New England Revolution goalie Matt Turner and snapped the ball into the net.
He then sprinted to the sideline, ripped off his jersey, slid on his knees, and celebrated his goal.
Alone.
Unbeknownst to both players, the linesman had raised his flag to signal Burke was offside. Every other player on the field knew the play was dead and simply just watched Burke have his moment.
