My son went through this is senior year of high school. He hyperextended his knee, coming down from catching a pass did not hear a pop in the ACL test was inconclusive told to go get an MRI. The MRI revealed a tear and meniscus damage at the time I did not think it was that bad, it was painful but not thought to be a devastating injury at first but the biggest thing about all of this is the rehab which is crushing to an athlete
It’s different for different people let’s just keep track of it and see how long it actually takes him to get back on the field. I think we might be surprised.
