Once a player enters the portal, the school has the right to pull his scholarship. If he returns from the portal and stays with his original team, the coach has the option to give him his scholarship back or give it to someone else. The deal with HT is that he's one year away from being eligible for the NFL draft and if he transfers to another P5 school, he will have to sit out unless the NCAA changes their transfer rule, which is under consideration. There is also the issue with the SEC rule that covers players transferring within the conference. Another obstacle he has to overcome. Saban is hoping the NCAA changes the transfer rule so HT can play at Bama this year. That's why HT is not at Bama right now.
