Colin Kaepernick kneels during the national anthem
Kaepernick kneeled for the first time in September 2016

According to reports in the United States, Colin Kaepernick has trained with the Las Vegas Raiders in order to return to the NFL.

The San Francisco 49ers player protested against racial injustice by taking a knee during the national anthem.

Since opting out of his contract, the quarterback has not played professionally.

He was a part of a Raiders tryout on Wednesday.

In October of last year, Colin Kaepernick filed a grievance against the owners of the National Football League because he believed they were conspiring to not hire him because of his protests. The grievance was settled in February of 2019.

Raiders owner Mark Davis said last month that he would welcome Kaepernick "with open arms" and that he "deserves every chance in the world" to become a quarterback in the NFL again.

If it aided his return to the sport, he would be willing to accept a backup role.

He told the I Am Athlete that he has to find his way back in.

If I have to come back in as a backup, that's fine, but I'm not staying there.
