Fan violence had broken out between Huracan fans at the game in the Mendoza province.
And the scenes took a turn for the worst when a gun was fired, hitting the Ferro head coach Mauricio Romero.
A tweet from the club later confirmed the injured Romero was "doing well and out of danger" after receiving tests at a local hospital.
The coach, who was treated on the pitch, has since given a statement to the police.
Huracan were winning 3-1 when the game had to be suspended late in the second half after the loud gun shot was heard.
Following the incident, Huracan said in a Facebook post that the infighting between fans is "ruining the club" and has asked for all those harming the club to "stay away so that real fans can return".
An official statement on Huracan's website read: "We are aware that we have been part of a barbarism that is difficult to understand and explain, which will mark the sports and institutional career of the professional team and our club.
"Once and for all, the leaders of our Argentine soccer must take exemplary measures that allow us to continue believing in this sport. The sanction already exceeds sports, requiring a political decision that severely punishes the unusual events.
"Our Institution will always watch over the values, integrity and health of our athletes, which allow us to pass the competences of the different disciplines. Today more than ever, those who direct the destinies of soccer must mark the way for us with actions so that we never experience a similar situation again."
