Wagner, the sixth pick in the 2002 draft by Cleveland, signed with the Warriors in late September after missing most of the previous two NBA seasons while recovering from an inflammation of his colon, which was removed.
He started well at Golden State during the preseason but quickly fell out of favor with coach Don Nelson. Wagner, who once scored 100 points in a high school game in New Jersey, played in just one game with the Warriors, scoring four points against Detroit on Nov. 11.
Wagner apparently struggled to adjust to the NBA's everyday grind, particularly lagging on defense. He was unlikely to get much playing time behind Warriors guards Baron Davis, Jason Richardson, Monta Ellis and even Anthony Roberson, an undrafted second-year pro.
