Spartans coach Tom Izzo announced the move Monday, saying Kaminski could not live up to obligations despite multiple opportunities. Izzo suspended Kaminski twice last season for a total of four games and two exhibitions.
Kaminski has not decided where he will transfer, according to a message he posted on his Twitter account.
He made a Big Ten-best .494 percent of 3-point attempts last year as a redshirt freshman. The 6-foot-8, 225-pound forward averaged 4.9 points, 1.5 rebounds and 12.2 minutes in 31 games.
