The Hawks made two minor roster moves on Tuesday.

Isaac Humphries was waived a day after the forward/center signed. The Hawks will retain the G League rights to Humphries, who played in his native Australia and Serbia, and he could eventually end up with the team’s affiliate in Erie.

The Hawks also signed C.J. Anderson, a guard who played four seasons at UMass. He averaged 10.6 points, 5.2 assists and 5.0 rebounds in 35.2 minutes as a senior last season. Anderson is expected to be in uniform when the Hawks host the Spurs in an exhibition game Wednesday at Georgia Tech’s McCamish Pavilion.
