The squad had already been on probation since November for serving alcohol to minors and making way too much noise at a party to end last season, resulting in fines and citations. Now the team, known as EGO (Eugene Gentlemen's Organization) is crying foul.
"We put on the longest shirts we had," pleaded player Kevin Minderhout. "We have some jerseys that are pretty long."
Minderhout said the team feels "the decision to end the team season was pretty heavy."
Ultimate Frisbee, which is akin to flag football and is popular as a club sport at numerous universities and high schools, has rules but no referees. Players are responsible for their own foul calls and are to resolve their own disputes.
The sport is non-contact. Points are scored by completing a catch into the opponents' end zone on a court measuring 40 by 70 yards. The Oregon team was considered No. 3 in the nation.
During the April 11 incident, one team went without shirts and five on the other side went without pants and underwear.
Someone complained. The club sports executive committee, a review board of five students, held a hearing Monday. Team members didn't do themselves any favors by saying there was nothing wrong with playing without pants.
Sandie Hammerly, executive director of the sport's governing body in the United States, the Ultimate Players Association in Boulder, Colo., said she and the association's championship director, Will Deaver, support the punishment.
"You have to wear clothing - it's in the rules," Hammerly said.
