The unanswered question as far as I know is... has the NCAA and/or the B1G (not sure which) officially granted his request for a medical redshirt yet?
If the request has been granted, then yes - he still has eligibility and is out of the draft unless he declares for the draft, for which the deadline is today.
If the request has NOT yet been granted, then I assume he's in the draft, since as of right now he is out of eligibility. Then when the request is finally granted (which I assume it will be), he can then remove himself from the draft.
