I hope you never have a knee injury. It sucks. But what sucks even more is reinjury. Control your urge to play again. Professionals get back on the field in 4-6 months and thats their full time job.
Trying to get back on the horse in that timeframe without a professional support structure will result in reinjury. Running on a treadmill and some PT does not mean you are ready for a contact sport. Your reflexes and natural balance take a while to reset to baseline.
I hope this message saves someone from reinjury
