The University of Wisconsin is taking a hard look at stadium entry rules after an attendee at a football game against Nebraska was photographed wearing what appeared to be a President Obama mask and a noose, reports CBS News.
Wisconsin athletic director Barry Alvarez said in a statement that he was "deeply troubled by the incident ... and sorry for the harm it caused."
University staff asked the fan to remove the offensive parts of his costume during the game and he did comply.
Meanwhile, a photo of the fan made its way around on social media.
Alvarez also said he was determined to make sure "nothing like it would happen again." He met with community leaders and students on Wednesday to discuss stadium policies.
The school's current policy on masks and costumes is that a fan cannot wear a mask at the stadium, but must take it off when they are entering the stadium.
The university announced they planned to revise the policy by the time Wisconsin plays the Illinois on Nov. 12.
The university released this statement in response to the fan's costume.
