The injury occurred during the first minute of Sunday's 64-61 victory after Akok had blocked a shot and was running back down court.
The extent of the injury was confirmed Monday by an MRI.
Akok will undergo surgery later this week and will miss the remainder of the season.
Coach Dan Hurley was emotional discussing the injury after the game.
"It was a big win, but there's no joy in it when something like that happens in the first minute. Sports is brutal sometimes, life is brutal sometimes," he said.
Hurley also tweeted about Akok's injury:
