BRUNSWICK (AP) — Bowdoin College’s nationally-ranked men’s tennis team will forfeit its next four matches and won’t be allowed to participate in postseason play for what school officials call a hazing incident.

The Portland Press Herald reported the sanctions were announced Wednesday in a letter from Dean of Student Affairs Tim Foster and athletic director Tim Ryan. Details of the hazing were not released.

They said no one was put in physical danger and blamed the incident on “poor judgment.”

Foster and Ryan wrote that the matter was brought to their attention by a student not affiliated with the team. After interviewing team members they found the school’s “well-articulated and frequently explained policy that prohibits hazing” was violated.

The Division III Polar Bears are ranked sixth in the country with a 9-2 record.
