I must have missed all those NBA, MLB, NHL, and European soccer professional athletes who have been dying from these undetected heart ailments post-COVID... they've all been back practicing and competing for a couple months now...
Maybe professional athletes are immune?
Regardless, the health protocols I saw posted by the Big 12 indicated that athletes would be tested three times a week and those who test positive would not be eligible to return to action until (obviously) they have two consecutive negative tests, an EKG, troponin blood test, echocardiogram, and a cardiac MRI. Seems fairly comprehensive to me...
