UCF Athletics said in a statement that Terry Mohajir, its vice president and director of athletics, apologized to Kent State for the school’s “unfortunate” post, which was made following the Knights’ 56-6 win over the Golden Flashes.

Paired with a photo showing UCF quarterback John Rhys Plumlee on the phone, the post stated, “SOMEONE CALL THE NATIONAL GUARD.”

The since-deleted post was made with the intention to reference a famous moment from 1996 during an NFL game between the Denver Broncos and the New England Patriots, the UCF statement said. In the sideline clip — with the final score 34-8 in Denver’s favor — Broncos tight end Shannon Sharpe pretends to call the president, saying in part, “President, we need the National Guard (...) call the dogs off, send the National Guard.”

On May 2, 1970, the National Guard was called to Kent, Ohio, to disperse anti-war protests being led in large part by Kent State University students. As classes resumed May 4, a day after much of the protesting had been broken up, thousands of demonstrators returned to the university’s campus. National Guardsmen opened fire into a crowd of protesters there, killing four students and wounding nine, one of whom was left paralyzed.
