This jersey's distinctive mark dates back to a match played on July 8, 1984, at Boca's stadium. The home team, in freefa...ll due to its institutional problems, had to play with the now-famous jersey with painted-on numbers. Some say this was because Atlanta only brought their blue jersey with yellow trim, while Boca only had their home kit. Since the jerseys were similar, they had to resort to a white training jersey without a number, which they then applied with marker, which faded as the minutes ticked by. Others, the majority, attribute it to the home team's financial collapse. The final score was 2-1 for Atlanta. This event became known as "El Fibronazo".
