As has been said many times before, his original recovery time was said to be 12-18 months. He hasn't even reached 12 (that's May 10th). They have also said that they have a set date that he won't be allowed to return before, and they won’t reveal that date (most assume it's the one year mark). They have also said that they have had to tell him to slow down because he feels good and wants to push it, and any little setback they would have to start all over. If the date is the one year mark, the Avs would have to make it out of the 2nd round before there is any possibility of him playing.
If it were me, I wouldn't let him play till next year at training camp. Let him heal the full 18 months. Putting him in, in the most intense time of the season, when he's coming back from a really sensitive injury/surgery, and hasn't played in 2 years, seems like a really bad idea.
