Boca Juniors have failed in a bid to delay the resumption of the Superliga season, after claiming a clash with players' international commitments left them at a disadvantage.
The next full round of Superliga games is billed for January 24-26, ending a six-week mid-season break, but Argentina Under-23 players will be engaged in qualifying for the Olympic Games.
Argentina play Colombia, Chile, Ecuador and Venezuela between January 18 and January 30, looking to advance to the next stage in February and close on one of two CONMEBOL places at Tokyo 2020.
