Patton picked up the injury when lunging for a mark in the opening quarter of the Hawks' loss to Collingwood on Friday night.
GM - Football Graham Wright said the club was disappointed for the key forward who has endured a wretched run of injuries throughout his career.

"Obviously this news is really disappointing for Jon and the club," Wright said.
"His frustration and emotion was evident on Friday night so you can see how much this means to him.
"The positive news is that we should see Jon back on the park in a month and he'll undertake his recovery with the support of the club, as we continue in the hub environment.
"We're confident that he will do all the right things in his recovery to ensure we see him back out there as soon as possible."
