Matt Zenitz of al.com had the first report. Yes, Mo Hasan is the first of the quarterbacks from the 2019 Vanderbilt Commodores to enter the transfer portal. Before the outrage rises, it is very possible that Vanderbilt’s medical staff is the cause of this transfer, not Derek Mason. Or, yes, it could be a sign that Mason is losing the faith of the locker room even though the late gains in recruiting and lack of transfers from players expected to contribute meaningfully next year says otherwise.
Whether Mo Hasan can safely play football again is not something any of us are equipped to assess.
