its probably an enlarged heart or an abnormal arrhythmia over the last 10 years a handful of guys have been found to have irregularities of varying degrees since the league started mandatory testing in 2006 .Robert Upshaw's draft stock is about to plunge significantly. It was reported he has a heart issue of some kind: http://www.cbssports.com/nba/eye-on-basketball/25206551/robert-upshaw-flagged-at-combine-for-heart-issue-has-suspended-workotus
Wonder if related to his past drug usage. He may still get picked up in the 2nd round, but I see no way get is a 1st rounder now.
only isaiah austin who had marfan's is the only guy i think couldnt play.
jeff green was diagnosed a few years ago and needed surgery , the grizzlies gave up a 1st rounder for him this past season...it depends on the severity and the type, which isnt known yet.
