Very cautious optimism in the interview with Leslie McDonald from WTVD. There is surgery scheduled for August 3rd but right now there are signs the torn ACL might not be as severe as first feared. McDonald said he is able to walk on it, there is minimal pain and swelling and he has full range of motion. That would explain why McDonald tweeted he was fine a few hours after it happened.
Since I am a blogger, not a doctor(Jim!) I am not sure if this means McDonald could come back in time to play this season or not. UNC has McDonald listed as out "indefinitely" which is the truth for the moment until a full timetable for recovery can be established. In the meantime we can hope for the best as it pertains to the coming season with the most important thing being McDonald recovering to 100% regardless of when that happens.
