If both uniformed goalies are removed, the EBUG, or Emergency Backup Goalie, takes over. An EBUG is a player provided by the host arena but available to either team.

They're on a one-day contract, don't normally dress (get into gear), and usually just sit back and watch the game while eating a hot dog. It's typically a local rec league goalie/coach/staff member.

They sit in the press box unless a goalie gets hurt, then the equipment guys get the EBUG a jersey and he gets into his gear just in case he gets called in, but he has to stay in the locker room until or unless that happens.
