Foster was one of two K-State players suspended last month for unspecified violations of team rules. He missed three games before returning on Feb. 14 for a win over Oklahoma.
[daily_cut.college basketball]"Marcus and Tre have been unable to live up to the standards that we expect of our players," K-State head coach Bruce Weber said in a statement. "It is a privilege to represent Kansas State University and there are consequences when players don't live up to those expectations. Hopefully, they will learn from this experience and make the necessary progress to continue their basketball careers elsewhere."
Foster, a 6'3" guard, averaged 12.5 points, 2.3 rebounds and 1.9 assists as a sophomore, one year after he was an All-Big 12 second-team selection.
Harris, a 6'5" guard, averaged 3.8 points in 10.0 minutes over 21 games this season.
Thomas, a 6'0" guard, played in 52 games over his time at K-State, averaging 3.7 points, 3.0 assists and 2.6 rebounds.
"As for Jevon, he has worked diligently to succeed in our program both athletically and academically," Weber said. "He has made tremendous strides during his time at K-State but he's come to the decision he wants to be closer to home. We wish him the best as he moves forward in his college career."
Kansas State finished 15-17 (8-10 Big 12) after losing to TCU in the first round of the conference tournament earlier this month.
