While ESPN's Shams Charania reported Tuesday that the Denver Nuggets agreed to acquire big man Jonas Valančiūnas in exchange for Dario Šarić, the former might not play in the NBA next season.

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.

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.
