Oregon State forward Eric Moreland will miss 14 games this season and Devon Collier will miss one for violating team rules.
Moreland and Collier were both suspended indefinitely by coach Craig Robinson in July. He announced the dates the suspensions would be lifted on Tuesday during the team's annual media day.
Collier will be eligible to return Nov. 13 against Portland, and Moreland will return for the Jan. 9 home game against Stanford.
Moreland averaged 9.4 points, 10.4 rebounds and 2.5 blocks per game for the Beavers last season. Collier averaged 12.6 points and six rebounds.
Robinson did not disclose the reason for the suspensions.
