According to University of Michigan 2020 quarterback JD Johnson, he was born with an undecided birth defect and that he will no longer be playing contact sports.
“I want to announce that as of today, my football playing career has come to an end. I was born with an undecided birth defect called a ‘coarctation of my aorta', which was diagnosed when I was 12. I knew following my senior season that I required an expansion adjustment to the stent I had inserted back then, which is scheduled for December 12th. My focus remained on winning the 1st Arizona State 6A Championship at Pinnacle High School. After going through a battery of tests and a complete evaluation of my cardiovascular system, the doctors discovered that I have issues that cannot be corrected through additional surgery. I was told that I did not meet the clearance standard to continue playing a contact sport for fear that my aorta could rupture or that not enough blood would get to my brain, causing a (potential) on-field stroke.”
