2020 QB commit JD Johnson got some bad news this past week. JD has a heart condition where he has to retire from football immediately. Per ESPN: the heart issue is called coarctation of the aorta, which was diagnosed when Johnson was 12. He was scheduled to receive an expansion adjustment to the original stent, but upon evaluation doctors found complications. Johnson then learned that playing a contact sport could rupture his aorta or limit the blood to his brain.
After news like that JD had to make one of the toughest calls of his life to Coach Harbaugh and let him know his dream of playing QB for the Maize and Blue will never happen.
