Yale University's basketball captain mysteriously left the school before posters accusing the team of supporting sexual misconduct were put up on around campus.

Jack Montague had led the Bulldogs to the top of Ivy League conference with two games left to play.

But officials at the elite New Haven, Connecticut, school say he won't be coming back to the court in the midst of a bizarre controversy.

It appears that no formal allegations have been made against him or other members of the team.

According to the Yale Daily News, posters have been put up around campus saying: 'I stand with Yale women. End rape culture. Don't support rapists.'

They have been put up alongside others that read: 'Yale Men's Basketball, stop supporting rapists.'

On Thursday a new set of posters expressing a similar message appeared Wednesday morning in the Sheffield-Sterling-Strathcona lecture hall.

On Friday the team warmed up on the court before its game against Harvard wearing T-shirts with Montague's nickname 'Gucci,' as well as the word 'Yale' inverted.

Forward Justin Sears told the newspaper they had ripped most of the posters down from around the university.

He added: 'We just wanted to make it as clear as possible that Jack is one of our brothers. He’s family to us and we miss him.'

Montague, his team and the university administration are yet to comment on the situation.

They would only say he will not be playing for the rest of the season.

The Yale Women's Center wrote a length status on Facebook. Their claims have not been substantiated.

The post read: 'In light of recent events, The Yale Women’s Center would like to express its sentiments on the Yale that we want to be a part of.

'Our Yale is a place of respect and a home to all. It is a Yale in which students can feel comfortable and forge meaningful relationships on the basis of mutual understanding and consent.

'We at the Women’s Center believe in this vision, and therefore have high expectations for the Yale administration to promote a culture of respect.

'Bearing this in mind, we wish to comment on the current campus conversation in hopes that we can create an atmosphere of respect and understanding during this time of healing. We recognize that FERPA and Yale policy prohibit Yale from commenting on the exact nature of the incident.

'Though the silence is deeply frustrating to us and surely to many of you, Yale's actions speak much louder than its words. It appears that Yale has expelled a high-profile member of a sports team in the midst of a pivotal moment in the season on the basis of sexual violence.

'While we can only speculate about these occurrences, we can comfortably say that, should all of this be true, this is progress.

'It is progress both in the sense that a survivor felt that coming forward was a viable option for them and that they got the decisive outcome that they fought for.'
