Harvey “experienced a symptom” Thursday requiring medical attention, Alderson told reporters. The injury is said not to be related to Harvey’s elbow or shoulder. Harvey may fly back to New York for further examination.
“No one really knows what’s going on,” catcher Travis d’Arnaud told 710 WOR in New York. “We’re all praying for him and hoping that it’s nothing too serious.”
The pitcher underwent Tommy John surgery in October 2013, and missed all of the 2014 season. He returned to pitch in 2015, albeit with a controversial innings limit.
Harvey went 13–8 for the Mets last season, with a 2.71 ERA and 188 strikeouts. In his career, the 27-year-old is 25–18 with a 2.53 ERA and 449 strikeouts.
The Mets open the 2016 season against the defending champion Kansas City Royals on April 3.
