Jirobacchi’s side lost a game to a lower-league team and were relegated after a 0-0 draw at the hands of Juventus on Sunday, while Juventus midfielder Gianlui Buffon is in a serious but not life-threatening condition in hospital.
Juventus were relegated to Serie B after being promoted from Serie A for the first time since 1998, and the news comes after Buffon, who missed Sunday’s 1-1 draw at Milan, was sent off by referee Mario De Laurentiis after he punched a referee in the face in the 71st minute of the game.
Juventus defender Gianluidino Jirovski was shown a straight red card for his role in the incident.
He was taken off on a stretcher and later had his ankle and wrist cuffed as the crowd of 1,717 booed.
“We’re all angry, but at the same time, we know that this is not the end of the story,” Juve manager Massimiliano Allegri said.
“We’ll see what happens in the next 24 hours.”
The club announced on Tuesday that Jiroski had received a five-match suspension.
Bruno Mauri, an Italian Football Association (IFPA) vice-president, called for the disciplinary committee to look into the incident as it would be “a serious incident and could result in the player facing an expulsion from football”.
“It is a serious issue for Italian football,” Mauri said.
In a statement, Juventus said: “Juventus Football Club has received a complaint of an elbow to the face of Gianluio Jirosencic.
The incident happened at half-time and the player received a four-match ban.
“A disciplinary committee will be set up and an investigation is currently under way.
“We would like to thank all the supporters for their solidarity.”
“The players are still in hospital and will undergo further tests, including x-rays and a CT scan.”
Juve lost the game, 1-0, on penalties after a goal from Dani Rodríguez led to Milan scoring the opener.
Jirosini had already been sent off in the second half for a second straight game for the Italians, and Allegri described the incident on Sunday as “an absolute disgrace”.
“This is the most horrible thing that I’ve seen in football in a long time,” Allegri added.
Milan manager Francesco Totti said he was “disappointed” by the decision to send the midfielder off.
Totti said it was “an embarrassment for Juve, a real shame for football” and urged the disciplinary authorities to act fast.
After the match, Jiroski tweeted: “The only reason for my suspension is the one I gave to the referee, who made a mistake.”
