Croatia forward and 2014 NBA draft prospect Dario Saric has agreed in principle to a three-year deal with Turkish powerhouse Anadolu Efes, a source close to Saric told ESPN.com on Monday.

The deal will have a player option for the third year. Saric is expected to receive and sign a contract in the next 24 hours.

The move will essentially prohibit Saric from playing in the NBA for a minimum of two years, the source added.

Saric was widely considered a top-10 prospect by the majority of teams in the NBA. He averaged 19.3 points, 9.3 rebounds and 3.8 assists per game for Cibona in the Adriatic League this year.
