*confused. he signed an ato with the stars?
Teams are required to have a EBUG in attendance and ready to suit up at their home games. This EBUG can be signed to a ATO by either the home or visiting team if that team loses both their starting and backup goaltenders during the game. The EBUG then become the third goaltender for a team during the game.
O’Brien (along with others) is one of the designated EBUG goaltenders St Louis provides during their home games. Home teams only provide one official EBUG, and usually have a list of multiple players they switch among during the season.
Because O’Brien was signed by Dallas to an ATO pre-game he is not acting as a EBUG this game, being the #2 goaltender for the Stars. He’s also not acting as a EBUG for St Louis this game. It’s likely the Blues have another goaltender serving as the EBUG tonight since O’Brien is unavailable.
If Wedgwood and O’Brien are both injured in game, or St Louis loses both of their goaltenders, then the third goaltender added by either team would be a EBUG.
