“"This offseason, I've been experiencing symptoms that have left me feeling drained and lethargic. I am working with doctors so I can better understand my condition. Until I can get my health back to a place where I feel I can perform at an elite level and help my team, I will not be joining the Blackhawks for training camp. I do not have a timetable for when I will rejoin the team. I am extremely disappointed, but it wouldn't be fair to myself or my teammates to attempt to play in my current condition.”
