Matt Harvey Has Non-baseball Medical Issue, Could Miss Opening Day

ESPN.com:

New York Mets right-hander Matt Harvey is dealing with an undisclosed medical issue that may place his Opening Day start on Sunday in jeopardy.

General manager Sandy Alderson declined to specify the issue, other than to say it was not related to an elbow or shoulder or anything else orthopedic. Harvey reported the issue to Mets personnel early Monday after a symptom unexpectedly arose, Alderson added.

"It's a non-baseball medical issue that we have to address," Alderson said after Monday's 3-1 loss to the St. Louis Cardinals. "It came up this morning as far as I know. There will be some follow-up tests and consultation that will take place over the next couple of days."

Asked if there is any gravity to the undisclosed issue, Alderson added: "I think it's a little early to attach any level of concern. ... I think we need to wait for more medical information before we decide it's of concern, or great concern, or no concern."

Harvey will be scratched from Tuesday's Grapefruit League start against the Miami Marlins. That had been slated to be his final tuneup for Opening Day opposite Kansas City Royals right-hander Edinson Volquez at Kauffman Stadium in a rematch of Game Nos. 1 and 5 of the World Series.

The fact that Harvey could miss his Opening Day start and the Mets aren't saying why is a really bad sign.
