Moynihan and McCarthy attending.
Not Devils related, but I assume Alex Turcotte isn't listed since the Kings loaned him to play in Germany.
Edit: Forgot about Trevor Zegras and Nick Robertson as well, but they're under pro contract so their teams might have something else in mind. They were on last year's team so they probably have spots if they're available.
Silly thought, would the Devils allow Hughes to participate in the WJC depending on the NHL start date? It'd be like Ryan Nugent-Hopkins playing in the 2013 WJC during that lockout after playing 2011-12 in the NHL.
