while i think perk might indeed be suspended for game 4, i think its not so easy a case. you could argue the contact was almost accidental - perk should have put his forearm down, but it seems a lot more incidental than anything. plus, yeah, pietrus flopped big time. he might still get suspended (technically, he did hit him above the shoulder), but they do interpret these things, so i think there's a decent chance he won't.
