Colin Kaepernick's fans and supporters have stated countless times that they believe that he is being blackballed by the NFL for his national anthem protests last season.  For now, Kaepernick remains unsigned.

As this year's NFL season begins, Kaepernick's supporters are sounding off about the football star.

According to NBC Bay Area news, the Detroit alumni chapter of Kaepernick's fraternity, Kappa Alpha Psi, marched for about a mile Sunday just outside Ford Field, where the Lions played the Arizona Cardinals, in support of the activist player.

Eric Brown, a former president of Kappa Alpha Psi in Detroit, said that Kaepernick using his platform to protest police brutality was not only right, but necessary. 

"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 Brown referring to when the Seattle Seahawks player was held at gunpoint by police who allegedly threatened to “blow [his] f*cking head off."

Brown said that this will not be the last time members of Kappa Alpha Psi will unite to protest the treatment of Kaepernick.

They plan to have similar gatherings in Dallas, Texas and Atlanta, Georgia before NFL games in the future.

NFL players also showed their solidarity with Kaepernick on the first NFL Sunday of the season.

San Francisco safety Eric Reid took a knee during the national anthem while several of his teammates stood around him. Reid also supported Kaepernick's protests last season.

Justin Britt of the Seattle Seahawks protested with teammate Michael Bennett Sunday during their game against Green Bay.

Bennett's younger brother, Martellus, a tight end for the Packers, stood and raised his right fist in the air during the anthem.

In Tennessee, Raiders running back Marshawn Lynch also sat during the anthem.

Although Kaepernick isn't on the field, the spirit of his protest seems alive and well.
