Jarryd Hayne needs to have a cyst removed after minicamp. He is still able to practice, so this would seem to not be a huge issue.
The San Francisco 49ers wrap up their mandatory minicamp Thursday morning with a 9 a.m. practice session, and at that point most of the players will go their separate ways. Jarryd Hayne is headed back to Australia for the next few weeks, and will return when rookies report for training camp later next month. Cam Inman is reporting Hayne said he will be having a minor surgical procedure to remove a cyst from his foot.
