To ruin Shakespeare, I think this is much ado about practically nothing. Without knowing details of the procedure, what it was for, what the damage was, what other structures got involved and so forth, it is impossible to say what the recovery is going to look like. It could be a few days and it could be much longer. However, since the Cubs seem to have learned their lesson about overly agressive statements of recovery, I'd guess that they're pretty sure he'll be back up and running in the timeframe that they say. (BTW - since sources and knowledge are being questioned here, I get this from my wife who is a physical therapist with about 15 years experience helping people recover from this kind of injury, including olympic athletes). What I CAN guarantee is that nobody here, with the information that we have available, is going to know more about what the recovery time is going to look like than the Cubs and the doctor who performs the surgery.
