The bottle that split open the head of Chris Brown’s GIGANTIC bodyguard Wednesday night was thrown by a member of Team Breezy.

Multiple witnesses say … Brown’s hired muscle, Big Pat, was standing in front of Chris when the bottles started flying. We’re told Big Pat turned towards Chris … when someone in Brown’s own entourage fired a bottle intended for Drake’s party, but missed … bad.

Instead, the bottle connected with Big Pat’s face at extremely close range … and opened a giant bloody gash on his forehead. Pat ended up suffering the worst injuries of anyone in the club — ironically from his own posse.

Pat received emergency medical treatment for the wound — but he appeared fine the next day.
