On Monday, Purdue University suspended 14 students who attended a party in a residence hall Saturday night because they violated the school’s precautions to lessen the spread of coronavirus.

According to Purdue, 13 of the students are student-athletes.

The school’s Code of Conduct penalizes students who violate the “Protect Purdue Pledge” — which calls for mask wearing and social distancing — at on- or off-campus gatherings.

In a statement, the athletics program said the party involved “out of season” student-athletes.  The department said it was working with the university, calling the incident “unfortunate.”

In a statement, Purdue President Mitch Daniels said, “The fact that this episode involved student-athletes can make no difference. At Purdue, we have one set of rules for everyone.”

Previously, Purdue suspended 36 students for violating Protect Purdue Pledge guidelines while attending a party the week before school began in August.
