“During our discussions with Jared and his agent, Mark Bartelstein, we were made aware that he played with pain for a significant part of last season due to this injury,” said Wizards President Ernie Grunfeld. “After jointly consulting with our team doctors and several specialists, we collectively determined that this proactive approach was the best course of action to have him ready for the upcoming season and to prevent the risk of further injury.”
