Oklahoma City, OK - General manager Sam Presti announced Thunder forward Andre Roberson has been assigned to the Tulsa 66ers of the NBA Development League on Tuesday.

Roberson, the 26th pick in the 2013 NBA Draft, has appeared in six games for OKC and averaged 0.8 points and 1.7 rebounds in 6.5 minutes per game.

The 6-foot-7 Colorado product has shown promise on the defensive end and is already an outstanding rebounder, but lacks offensive prowess. Roberson will have significantly more playing time to work on that facet of his game in Tulsa.
