Serie A club Lazio and their president Claudio Lotito have been referred to Italy's federal court after an investigation into violations of coronavirus protocols, the Italian Football Federation says.
The FIGC said on Tuesday that Lazio, Lotito and two club doctors are accused of "violations of federal regulations and a lack of observance of the health protocols in force".
The allegations include failing to promptly report positive cases to health authorities and failing to stop three players from attending a training session after receiving positive tests.
They are also accused of twice failing to enforce a mandatory 10-day isolation period on an asymptomatic player, who was subsequently involved in a Serie A game.
Lazio spokesperson Roberto Rao said the accusations were contested.
"We trust in sporting justice, which will be expressed in the appropriate offices, so that the correct reconstruction of the facts is re-established," he said.
An investigation was opened on November 3 over potential violations of protocols regarding COVID-19 testing. The club's training ground was inspected and swab test results were seized.
"It's a matter related to the interpretation of the rules around the subject of COVID-19, both in terms of the duty to communicate to the local health authority and the practical interpretation of some parameters of the medical protocol," Lazio said in a statement.
