It isn't very likely that we would hear anything. Remember what Quinn said the other day? Can you imagine how pumped up the crowd would be if Sundin and Nolan hit the ice with no pre-warning for the fans or even better the Sens?
Who knows maybe Nolan will be in the lineup tomorow he has been skating. Tell me that wouldnt throw the Sens game plan if Nolan was a last second addition to the lineup. Probably not going to happen but that would be sweet if it did.
