The incident happened midway through the Yankees' 5-0 win. Manager Joe Girardi said the fan appeared intoxicated and fell into a part of the dugout where no players were at that moment.
"It kind of freaked me out, actually," Girardi said. "I think he tried to jump in, but he was probably not even in a state to be walking."
Girardi said the fan fell twice, landing on his ribs at first then going down again when he tried to stand. The fan was escorted from the stadium by two members of law enforcement.
"Let's just say he shouldn't have really been doing anything," Girardi said.
