Great news, per Adam Schefter:
"Michigan’s potential first-round pick Mo Hurst has met with cardiologists at University of Michigan and Harvard, and they have cleared him to resume playing football, per league source. Hurst will do a full workout at Michigan's pro day on Friday."

Looking forward to seeing him play. Despite the concerns, he should still be a 1st round pick and have a productive NFL career.
