The Uruguayan Football Association (AUF) has postponed all matches this weekend after the death of Penarol fan Hernan Fioritto.
Fioritto was reportedly shot by rival Nacional supporters while celebrating Penarol's 125th anniversary in the town of Santa Lucia on September 28.
After news of the supporter's death on Friday, the AUF has responded by suspending all football in the country this weekend.
An AUF statement read: "The Executive Council of the AUF, after the lamentable fact of the death of a football fan aged just 21, has decided to suspend all activities organised by the AUF for this weekend.
"As important to all Uruguayans as football is, there is nothing more important than the life of a human being and young football fan.
"It is impossible to return the life of Hernan Fioritto, let alone repair the damage and pain done to his family and loved ones.
"We have to think and reflect on what is the limit of passion, admiration and feeling for a football club.
"The Executive Council invites all involved in football and our society, without exclusion of any kind, to unite and work together, redoubling efforts and actively proposes with concrete action to save our main sport and passions."
