Mets shortstop Jose Reyes will be examined for the next several days in New York.
Reyes was scratched from Friday's Grapefruit League game and is scheduled for follow-up blood tests on Monday after physicians detected a possible thyroid hormone imbalance.
An overabundance of thyroid hormone introduces a host of dangerous symptoms including tremors, weight loss, sleep loss and irregular heartbeat.
According to doctors contacted by the New York Post, prognosis with treatment -- given early detection -- is excellent.
