Colin Kaepernick's protest movement rolled on without him Sunday, as his fraternity marched in Detroit and players around the NFL sat or knelt during the national anthem.

Kaepernick remains unsigned after opting out of his contract with the 49ers. His supporters believe he's being punished for protesting police brutality by refusing to stand during the national anthem last season.

About 50 members of the Kappa Alpha Psi alumni chapter in Detroit marched about a mile Sunday in a peaceful protest that ended just outside Ford Field, where the Lions hosted the Arizona Cardinals.

"When you look at some of the recent incidents like what happened to Michael Bennett in Las Vegas , it validates the stance that Colin Kaepernick has taken," said Eric Brown, a former president of the fraternity's alumni chapter in Detroit.

Brown said Kappa Alpha Psi planned to have similar gatherings in Dallas and Atlanta before future NFL games.
