The Oklahoma City Thunder have agreed to a one-year, non-guaranteed deal with free agent forward Talib Zanna, league sources told RealGM.

Zanna spent last season with the OKC Blue in the NBA D-League, averaging 13.3 points, 11 rebounds and 60 percent field-goal shooting in 50 games. Zanna joins Dez Wells as training camp invites to the Thunder.

Zanna played for the Thunder and Cleveland Cavaliers in the July summer leagues.

A 6-foot-9 big man, Zanna went undrafted out of Pittsburgh in the 2014 NBA draft.
