Nocerina Derby Game
The club’s sporting director, Luigi Pavarese has since attempted to explain the injuries as genuine, saying: "The lads went onto the pitch without warming up, which caused the injuries."
Nocerina’s "Ultras" issued a statement on Monday saying they did not issue any death threats, but wanted to issue an "unmistakeable message" and "give voice to an unfair act imposed on the fans".
Local judicial authorities have since begun an inquiry, with around 30 Mastiff fans reportedly at the centre of the investigation.
"This has caused enormous damage, it’s an extremely grave matter," Lega Pro director general Francesco Ghirelli told Italian television.
"We have to reflect on how to prevent these indecent spectacles. It’s a disgrace.
"We will wait for the sporting tribunal to judge this episode which has done huge damage to the Lega Pro."
