The second flipped Dario Sarič to Sacramento for Jonas Valančiūnas, seemingly solving the Nuggets' backup center problem that's persisted for a few years now. However, new reports indicate that deal may not get done as Valančiūnas may not even play in the NBA next year.

Donatas Urbonas of BasketNews first reported Thursday that Valančiūnas is considering leaving the NBA to play for Greek club Panathinaikos Athens. Longtime NBA insider Marc Stein confirmed Urbonas' report that a return to Europe is enticing for Valančiūnas, a 33-year-old center from Lithuania.

The Nuggets landed the former first-round pick in a trade that sent Dario Saric to the Kings, but the deal cannot be completed until the new league year begins July 6.
