Legendary NFL quarterback Brett Favre says Colin Kaepernick will be remembered as a hero.

"It's not easy for a guy his age—black or white, Hispanic, whatever—to stop something that you've always dreamed of doing and put it on hold, maybe forever, for something that you believe in," Favre told TMZ Sports. "...I can only think of right off the top of my head, Pat Tillman is another guy that did something similar. And we regard him as a hero, so I'd assume that hero status will be stamped with Kaepernick as well."

Following the Sept. 11 attacks, Tillman retired from the NFL at age 25 to enlist in the United States Army. He died on April 22, 2004, in Afghanistan.

Kaepernick first kneeled during the national anthem in 2016. He has not played in the NFL in the years since.

Roger Goodell recently admitted he was wrong to disagree with Kaepernick's protest and stated he hopes that a team signs him. "Well, listen, if he wants to resume his career in the NFL, then obviously it's going to take a team to make that decision," Goodell told ESPN. "But I welcome that, support a club making that decision, and encourage them to do that."
