A fan attending Sunday's NBA Finals Game 7 at Oracle Arena was pushed over a second-deck railing during a postgame altercation and fell to the seats below, police said.
The man, said to be in his early 20s, was taken to an area hospital with unspecified injuries. He was listed in critical but stable condition early Monday morning.
Oakland police were interviewing witnesses and reviewing surveillance footage as part of an investigation into possible foul play, a department spokesperson said. Police said it's believed the man was pushed by another fan as the Cavaliers celebrated their 93-89 victory on the court below.
