Seems he's out, apparently not ready for the Vuelta.
Florian Vermeersch, a Classics prospect with a fast finish, will fill in for Ewan and try his hand in the sprints, leaning on Frederik Frison for support. He is one of four Grand Tour debutants in the squad, alongside Sylvain Moniquet, Maxim Van Gils, and Andreas Kron, who has enjoyed a brilliant first WorldTour season, with stage wins at the Volta a Catalunya and Tour de Suisse.
Harm Vanhoucke will be aiming for increased consistency and a possible general classification effort after impressing at the past two editions of the Giro d'Italia, while the eight-man squad is rounded out by Steff Cras and Britain's Matthew Holmes.
He can ride painfree, but not sprint. Because of his low unorthodox position while sprinting there's a lot of pressure on his shoulder and collarbone. So not fit enough to start the Vuelta.
Lelangue also talked a bit about Ewans contract extension saying it isn't about the money for him, more about him being the only leader in the TDF squad and LTS being the only team wanting to give that to him. That and having a dedicated and strong leadout train.
Ewan broke his collarbone in four places, so it was a race against time to be fit for the Vuelta - It will be interesting to see the rest of his program - He always rides well at the Tour of Britain in which the team is not entered.
