Earlier today, Buster Olney of ESPN reported that the San Diego Padres would be reviewed by MLB for not revealing enough medical information about Colin Rea and Drew Pomeranz in trades with the Miami Marlins and Boston Red Sox.
Later, Dennis Lin from the San Diego Union-Tribune confirmed that he had heard the same thing from his sources.
This could just end up with MLB outlining more specific rules for medical disclosures in future trades, but the Padres will need to keep an eye on this. There is a possibility that they could be reprimanded, including some sort of sanctions, if the league determines that A.J. Preller purposefully traded players he knew to be injured and did not disclose that information during the trade discussions.
