This is a new one.

The NFL Combine is in full swing this weekend in Indianapolis. Defensive linemen and linebackers are scheduled to work out on Sunday for scouts. But Alabama linebacker Reuben Foster, one of the best defensive players available, won't be there because he got sent home for being unable to wait his turn to get medically tested.

The news was first reported by ESPN's Adam Schefter. Robert Klemko of the MMQB provided more details: 

So Foster will be watching the Combine at home like the rest of us. Probably a bad move for a projected first round pick.
