The Thunder will get 7-foot center B.J. Mullens from Ohio State in exchange for point guard Rodrigue Beaubois from Guadaloupe and a future second-round pick.
NBA deputy commissioner Adam Silver announced the trade Thursday night.
Dallas had taken Mullens at No. 24, and Beaubois went to Oklahoma City with the very next pick.
Mullens averaged 8.8 points and 5.7 rebounds in his only year of college before making an early entry into the NBA draft. Beaubois has been playing in the French Pro A league the past three years after being discovered by NBA player Mickael Pietrus, who is from the same Caribbean island.
The Minnesota Timberwolves have traded second-round pick Nick Calathes to the Dallas Mavericks for a 2010 second-round pick and cash considerations.
The Wolves selected the Florida guard with the 45the overall pick. But with first-rounders Ricky Rubio, Jonny Flynn and Wayne Ellington already coming to a jam-packed roster, the Wolves really didn't have room for Calathes this season.
