Chicago Bulls and White Sox Chairman Jerry Reinsdorf has been released from the hospital, officials said.
Bassett Healthcare Network confirmed that Reinsdorf was treated and discharged Saturday morning.
Reinsdorf was taken to Bassett Medical Center after he experienced an "episode of lightheadedness" during his stay in Cooperstown, New York.
Officials said he was kept overnight as a "precautionary measure."
"All tests tonight indicate that he is fine," the White Sox said in a statement. "He is coherent, is resting comfortably and is communicating with his doctors and medical staff."
Reinsdorf is in New York to attend this weekend's Hall of Fame induction of former White Sox star Frank Thomas.
