According to Arthur Staple of Newsday via Twitter:
Anders Nilsson will join #Isles tomorrow. No plans to look outside org yet, though Nabokov injury seems to be 4+ weeks.
I was talking to a few Isles fans today about what might happen in terms of looking for a goalie via trade. For now, there’s no need to make a quick decision yet. The Bridgeport Sound Tigers do not play until Friday so at the very least Nilsson will keep the backup seat warm on Tuesday until a long term solution occurs. Nilsson by no means deserves a call up, but perhaps a game or two could help with his confidence. As for who the Isles could deal for does depend on how long Nabby will be out. 4+ weeks is a long time but if Poulin can handle the load, there may not be a need for a trade.
