EuroLeague basketball owners have rejected a formal offer from the NBA to merge into a single European operation following a meeting in Italy, Barcelona confirmed Wednesday.

The decision not to accept the NBA's proposal of a single Europe entity was made Tuesday in Cernobbio during a gathering of the EuroLeague's 13 shareholder clubs. They include Barcelona, Bayern Munich, Real Madrid, Olympiakos, Milan, Tony Parker -owned ASVEL in France and two Istanbul-based clubs.
