Round 3 schedule
Apparently the conference finals schedule will see Philadelphia play Game 1 in Pittsburgh on Friday, which would mean the Western Conference finals between Detroit and San Jose/Dallas would take place on Thursday night in Detroit.
I'll update as soon as this is confirmed, although a full schedule likely won't be available until the Sharks-Stars series is over. Game 6 in that one is tonight, with Game 7 to be played Tuesday.
UPDATE The Penguins-Flyers date is confirmed.
UPDATE A commenter notes NBC will not have a game this weekend due to their golf coverage, but I'd still bet we see that game played Sunday, perhaps in the evening.
