Gaines, 24, appeared in 35 games for the Utah Jazz last season, averaging 3.3 points and 1.2 assists per game. He got his big break following a stint with the Idaho Stampede of the NBA D-League, where he averaged 23.9 points, 4.7 rebounds, and 6.9 assists while making 52.2 percent of his field goal attempts. Utah elected not to guarantee his contract for this season, making him a free agent.
Injuries to point guards Jonny Flynn and Luke Ridnour necessitated Gaines’ signing.
To make room on the roster for Gaines, Minnesota waived combo guard Maurice Ager. In four appearances this season, he averaged 3.8 points.
