You aren't alone. Same here with 2011 grad, having knee surgery early Aug. Doctor says he should be good to go in 3 months, so early November should be able to participate in baseball if all goes as planned.
Question I have which also applies to you as well.
Is it a bad time to contact colleges regarding baseball? Does one get it out there that there is a knee problem? Do you just wait until fully healed then resume the process?
