Greece’s Thanasis Antetokounmpo will be able to show his skills when the Knicks open their Las Vegas Summer League schedule Friday, but The Post has learned it is expected to be the last American venue for their second-round selection for a while.

According to an NBA source, the Knicks drafted him with plans of stashing him in Europe for one season, even if he has a solid summer league showing. Antetokounmpo could have other ideas, and the Knicks claim officially no decision has been made yet. The Knicks have their first summer-league practice Tuesday in Las Vegas. Antetokounmpo was selected by the Knicks with the 51st pick, which they acquired as part of the Mavericks trade that sent Tyson Chandler to Dallas.

The Post reported last week a Greek team was interested in signing the 21-year-old brother of Bucks rookie revelation Giannis Antetokounmpo, known as “The Greek Freak.”
