Apparently he had a testicular torsion. My son had the same surgery in late July right before his junior year of high school football. He missed a month of practice. That was 10 years ago and I’m guessing Wake will optimize Hartmans progress. My prediction is he will be playing again by mid September.
How will not throwing for a month affect his performance? It won’t help. 80-90% mid September through mid October and back to normal after that.
Just a guess. I wish him the best and a quick recovery.
