NEW YORK, March 5 (UPI) -- New York Mets shortstop Jose Reyes will undergo tests in New York for what doctors believe may be a thyroid imbalance, a team spokesman said Friday.
Doctors ordered the tests after seeing the results of blood work on Reyes during spring training in Florida.
Reyes left the team's training site at Port St. Lucie and will not play again until results of further tests are known, the team spokesman said.
The tests may be done Monday.
"Further review of the (spring training) test is that there may be an imbalance in his thyroid levels," the spokesman said.
Reyes said he felt OK and didn't know whether he would be temporarily removed from the lineup.
The shortstop said he was told his test in Florida had a "higher level," an indication that he might have an overactive thyroid, mlb.com said.
"I don't know what's going on; this is the first time I've ever had something like this," Reyes said. "I have to be worried. I can't do anything."
Reyes underwent surgery last fall to repair a torn tendon in his right leg. He said the blood tests were unrelated to that problem.
"This is important, it's nothing about my leg," he said.
Reyes has hit .286 with 551 runs scored in 791 games with the Mets. He has also stolen 301 bases.
