Terry Francona didn't manage the Cleveland Indians on Tuesday night after complaining of chest pain while speaking to reporters before the game.
Francona was examined by the Nationals Park EMTs and remained at the stadium at the start of the game after it was determined he did not need to go to the hospital, according to the club.
The Indians are in the midst of a series with the Washington Nationals.
"I know that the doctors checked him out and so forth and they just felt it'd be better for him to probably go back to the hotel and he did," said bench coach Brad Mills. "Knowing him he was probably really agonizing during the game. But I think he's doing fine hopefully and we'll see how it works out for tomorrow."
The 57-year-old Francona has twice suffered a pulmonary embolism. In 2006 he joined others around baseball to educate people on deep-vein thrombosis.
