Kaminski had said on Twitter Saturday that he was no longer on the team and intended to transfer.
Last season, Kaminski averaged 4.9 points and 1.5 rebounds and shot a Big Ten-best 49.4 percent from three-point range in 12.2 minutes per game.
He redshirted his first season after injuring his shoulder as a senior at Medina (Ohio) High School. Kaminski was suspended two games twice last season for academics.
Kaminski reportedly suffered a back injury in a summer league game earlier this month.
Michigan State has lost three of its top four scorers -- two of whom, Gary Harris and Adreian Payne, became first-round NBA draft picks -- from a team that posted a 29-9 record and earned a No. 4 seed in the NCAA Tournament before falling to eventual national champion UConn in the Elite Eight.
I am no longer going to play at Michigan State, I will be transferring to another school but have not decided where yet — Kenny Kaminski (@KennyKaminski) August 2, 2014
