Tragic
I'm no medical expert, but from some browsing it looks like a lot of the potential conditions that can lead to these situations can be discovered with more thorough physical exams including X Rays, MIR's, etc. I would think that there will be more pressure for this type of pre/prep analysis moving forward - from players, parents, and therefore Universities, athletic associations, and/or conferences legal depts. Or, at minimum fights over appropriate construction of waivers.....
These things are expensive but worth it when lives are involved.

For the second time in the past few years, an NBA prospect was diagnosed with Marfan syndrome. It sucks that these guys had their professional careers halted so abruptly but in the grand scheme of things it's very fortunate that they had such in-depth physicals to discover them.
