In a statement, G2 explained that the players are leaving G2 "following successful negotiations for their transfer", without mentioning, however, their future destination.
The pair have been strongly linked with a move to French organisation Vitality, who are looking to enter the CS:GO scene with a team also featuring ex-EnVyUs duo Vincent "Happy" Schopenhauer and Cédric "RpK" Guipouy, and former aAa talent Mathieu "ZywOo" Herbaut.
Despite failing to live up to the hype, the team still won some international events during their first year, most notably the ESL Pro League Season 5 Finals and DreamHack Masters Malmö, but a disappointing start to 2018 saw the pair benched as Richard "shox" Papillon took the team's reins and brought in Edouard "SmithZz" Dubourdeaux and Kévin "Ex6TenZ" Droolans.
“I truly wish the best to NBK- and apEX for the next part of their CS:GO journey," G2 CEO and founder Carlos "ocelote" Rodríguez Santiago said in a statement.
"On a personal level, I love Nathan and Dan and I would have absolutely loved to have the opportunity to spend more time with them.
"They have been fantastic ambassadors for G2 Esports and the game. The decision to move them to the bench was not an easy one or a reflection of either player’s ability or character.
"Throughout their time at G2, they proved their ability and strength as players and professionals and I have no doubt they will continue to do so at their new home."
