One of the more well-known mascots in college sports will be out for a while after it was disciplined following an on-field incident.

The Stanford Tree posted on Twitter: “Stanford has decided to suspend the Tree for walking out onto the field last game with a sign reading ‘Stanford Hates Fun’. Tree socials will be inactive for the next few months. See y’all soon.”

Outkick reported that a party earlier this fall in Palo Alto that got out of hand was blamed on the band, but it was not an official band event and the person who hosted the party was not an active member of the band.

Ever since, the Stanford administration has tightened the reins. It has taken a more active role in the band’s performances and has taken more control what the band can and cannot do.

In what seemed to be direct response to the administration’s new policies, the band unfurled a banner during its performance on Saturday.
