Struggling New York Yankees closer Aroldis Chapman had an MRI on his Achilles on Sunday night, the results of which were negative.
Manager Aaron Boone made the announcement Monday, but said a trip to the injured list is still possible for Chapman.
"I think the IL is still very much in play. I just think we don't want to rush into it. ... We'll kind of see what we got," Boone said.
Chapman allowed a tiebreaking homer to AJ Pollock in the ninth inning of New York's 3-1 loss to the Chicago White Sox in Game 1 of a doubleheader Sunday in the Bronx.
