The defender has expressed his regret over the events that unfolded after the clash with the Rossoblu, in which he slammed officials for not awarding a penalty
The Italy international had to serve a one-match suspension this weekend after he confronted the officials for their decision not to award his side a penalty, following a handball by Andreas Granqvist.
But after looking back at the incident, Chiellini took the time to reflect on the situation and insisted he should have acted in a very different manner.
"Even if I could not play because of my injury, I sat out the one-match ban imposed after my reaction at the end of Juventus-Genoa," he told the club's official website.
"Now that the controversy about that match has gone, I would like to apologise publicly for the incident."
"Unfortunately, watching the game from the stands gave me more tension and after the end of the match I reacted too vehemently.
"We players should be the first who give a good example of how to behave on and off the field, so I wanted to apologise to all football and sports fans in general for my behaviour."
The 28-year-old then expressed his delight at the Old Lady's 2-1 win at Chievo on Sunday, despite not being able to contribute.
He added: "Yesterday we won a very important match on a difficult pitch like Verona, which in recent years had always created problems for us.
Juve currently top Serie A with a three-point advantage over second-placed Napoli.
