During Eastern Michigan's football game against Wyoming on Friday, protestors angered about the university's response to racism on campus gathered around the field.

As time expired shortly after 11 p.m. ET, the protestors – who numbered in the several dozens – linked arms and marched to midfield, holding their fists in the air. They then moved to the edge of the field along the sidelines and chanted "No justice, no peace" and also lyrics to Kendrick Lamar's "Alright" and Chance the Rapper's "No Problem."

Here's what happened before the protest moved onto the field

Earlier this week, protestors marched in EMU’s city, Ypsilanti, after some vile, racist graffiti turned up on the campus. There’s no reason to think the protestors have been anything but peaceful. They’ve definitely been passionate, though.

On Friday, protestors previously gathered in a concourse and reportedly marched around the inside of the stadium.

Update: a bunch of the EMU protestors are looking real serious about maybe coming onto the field... — Farmer Jones (@thefarmerjones) September 24, 2016

The protestors eventually started to push toward the field, as police tried to keep order.

EMU's president, James Smith, told CBS Sports Network in an interview during the game that the protestors wanted to walk around the track during the game, but that the school couldn't allow that for security reasons. Smith said the protestors don't think EMU has done enough to find whoever created the racist graffiti, to which Smith responded publicly, "We're working incredibly hard to find these individuals."
