Matt Harvey has been placed on the 15-day disabled list with right shoulder discomfort, the Mets announced.
Harvey has been referred to Dr. Robert Thompson in St. Louis for an examination that will take place on Thursday, the team said.
The Mets believe Harvey could have thoracic outlet syndrome, according to David Lennon of Newsday.
Dr. Thompson, according to his profile on the Washington University School of Medicine in St. Louis website, specializes in vascular surgery and thoracic outlet syndrome. Dillon Gee saw Dr. Thompson in 2012 to have artery damage repaired in his shoulder after doctors removed a blood clot.

Harvey has a 4.86 ERA and 1.46 WHIP over 92 2/3 innings this season.
He's allowed six earned runs and 15 hits, with seven strikeouts and three walks, during his last seven innings pitched spanning two starts.
Seth Lugo has been recalled from Triple-A Las Vegas to replace Harvey on the roster.
Well, damn. Although, if there's an issue, it will explain the up-and-down season he's been having... My hope is the Mets are being overly cautious and using this as a way to essentially skip a start, add an arm, and give Matt an extended break - since the next time he pitches, thanks to the All Star Break, could end up being two weeks from now. Whatever it is, though, I hope Matt is OK and I hope he gets right for the second half. Zack Wheeler isn't expected back until August, so - if Harvey is out for an extended period - there will be a gap in the rotation between now and then...
