Acy, 26, began the season with the Dallas Mavericks but was waived in November after a roster crunch forced the team to pursue a guard. Acy caught on with the Texas Legends, the Mavericks' D-League affiliate, where he averaged 17.3 points and 8.2 rebounds in 12 games.
The Nets signed him to his first 10-day contract on Jan. 10, and when it expired immediately gave him a second one. The 6-foot-7, 240-pound forward is slated to spend the rest of this season and next in Brooklyn, where so far he has put up 7.0 PPG and 2.7 RPG in 10 games.
The Toronto Raptors drafted Acy 37th overall in 2012 out of Baylor. The Nets are Acy's fifth team in five seasons. He has not remained with one team for more than a season since his rookie year in Toronto.
