Patton has been made to explain himself to the club, who have since released a statement to The Herald Sun.
The allegations in question surround several women who have come forward and stated Patton had sent them lewd photos on social media.
A club Integrity Committee is set to investigate the allegations and potentially solve the issue.
“Hawthorn Football Club is aware of allegations made on social media regarding the behaviour of Jonathon Patton,” the club’s statement said, per The Herald Sun.
“The allegations are of behaviour that does not reflect the values and standards of Hawthorn Football Club.
“As soon as it became aware the club addressed the matter with Patton directly and clearly communicated that any behaviour of this nature would not be tolerated.
“The club takes these allegations seriously and has referred the matter to Hawthorn’s Integrity Committee.
“Hawthorn promotes and advocates for equality and respect for everyone and demands this same behaviour from all involved with the club.”
Patton joined the Hawks ahead of 2020 after eight seasons and 89 games with Greater Western Sydney, and once again had his season riddled with injuries last year, playing just the six games.
