OAKLAND, Calif. — Authorities said a fan fell from the second to the first deck of Oakland’s Oracle Arena after the Cleveland Cavaliers’ Game 7 victory over the Golden State Warriors in the NBA Finals.

Oakland police spokeswoman Johnna Watson said the man in his early 20s fell over a railing because of a fight with another fan just after the game ended Sunday night.

Watson said the man was taken to a hospital in critical-but-stable condition.

No further details were immediately available.
