Jonathan Jeanne has been diagnosed with Marfan syndrome, which may be a career-ending ailment.

Jeanne was expected to be a first round pick in the 2017 NBA Draft.

Jeanne underwent an MRI while participating in the Chicago draft Combine in May that showed an abnormality in his spine that required follow-up examinations. 

Marfan syndrome is a genetic disorder that affects the body’s connective tissues. 

Jeanne worked out for an NBA team as recently as Wednesday when he visited the Toronto Raptors.
