Welcome to HSBBW PitchersParent!
You will get plenty of good advise on here from parents whose son's have gone through this exact same scenario. I know it had to be very hard for you to come and ask this disheartening question. This is a classic example of just how hard it is to play college ball and keep academics up at a high level Division of ball. As it really is at any college program.
He would have to sit this spring and I would imagine be given the option to Red Shirt. If he wanted to stay at the program and prove he belonged. Very admirable and many do it. Another option if he wanted to transfer and try to play somewhere this spring (2012) would be to a D2, NAIA, or JUCO program. Transferring to another D1 after this school year IS an option but he would have to sit next year which means he wouldn't be available to play until 2014. I may have some of these a little off kiltered but hopefully not by much
Hope this helps and good luck.
