The San Lorenzo-Huracan and Godoy Cruz-River Plate matches were postponed.
Over the weekend, all eyes in the Argentine soccer world were on the Copa Libertadores final between Buenos Aires-based clubs River Plate and Boca Juniors, which was postponed twice.
The championship match was initially scheduled for Saturday afternoon but was rescheduled for Sunday at 5:00 pm due to a series of violent incidents that forced officials to postpone the final of South America's premier club tournament.
On Sunday, South American Soccer Confederation (Conmebol) president Alejandro Dominguez said the final would be rescheduled once again to an unspecified date because the conditions for staging the match were inadequate.
At least 29 people were arrested Saturday due to violent incidents in the vicinity of El Monumental Stadium, forcing officials to postpone the second leg of the Copa Libertadores final.
In an initial incident, the team bus carrying Boca Juniors players to El Monumental came under attack by River Plate fans in Buenos Aires' Belgrano neighborhood.
Some objects thrown by the rowdy supporters shattered the vehicle's windows. Police responded by using pepper spray to disperse the assailants, but the action, according to team executives, ended up injuring some Boca players.
