The rumor was out shortly after Derrick Etienne was named to Haiti's long-list for its upcoming CONCACAF World Cup qualifiers:

It was confirmed by the Haitian Football Federation in a Facebook post explaining why the senior men's national team squad currently comprises only 18 players: Derrick Etienne has declined the call to join Les Grenadiers for the forthcoming September internationals.
The FHF cites "pressure from their club and their federation" as the reason why the New York Red Bulls' Etienne and New England Revolution's Zachary Herivaux turned down the invitation to join Haiti this time around.
There are an extraordinary number of players unavailable to the FHF for Haiti's September internationals. Etienne is by no means the exception. The decision to turn down this particular call-up need not be interpreted as a decision to turn down a senior international career with Les Grenadiers. But he won't be starting any such career this September.
