"I was inspired by a lot of the allies that were there (in Charlottesville) to stand up against hate in my hometown, and I wasn't able to be there to protest or to stand up against hate", Long said. according to ESPN.com.
"I support my peers", Long said on Thursday.
Jenkins asked Long what message he was trying to get across.
Long has been outspoken about the events last weekend in Charlottesville, which is Long's hometown.
"I've heard a lot of people say you need white athletes to get involved in the anthem protests", Long said afterward, per ESPN.
Long approached Jenkins before the game to tell him about his desire to show support during the anthem.
Jenkins raised his fist during the national anthem past year as well, following in the footsteps of Colin Kaepernick, who sat or knelt during the anthem throughout the 2016 season to protest police brutality and social injustice.
In addition, cornerback Ron Brooks kneeled during the national anthem, joining a handful of NFL players to do so, such as quarterback Colin Kaepernick, Seattle's Michael Bennett and Oakland's Marshawn Lynch. Last year, Brooks joined Jenkins in raising a fist for multiple weeks before being sidelined by a ruptured quad tendon.
"I think he understands that he could never necessarily know my experience as a black male, but in the light of all that's going on, as a white male, he understands that he needs to be an ally", Jenkins said.
"His biggest thing was that he feels that White me need to step up and be allies", Jenkins said. There are ways that white people can get involved in trying to stand up for equality. "I think it just continues to draw more attention and pull at people's conscious to feel more responsible in their role for how our country is right now and how each individual is responsible".
Earlier this week, Jenkins said he does not expect to see a large uptick in anthem protests as a result of what transpired in Charlottesville.
"There's always someone that will find a negative spin to anything that you do", Jenkins said.
"We talked to guys around the league and he was one of the few white men that was in those conversations and groups that wanted to see if he could figure out what was going on and see if he can fit by showing support in any kind of way. Because when you bring somebody who doesn't have to be a part of [the] conversation making himself vulnerable in front of it, I think when that happens, things will really take a jump".
Added Long: "I think I am doing the right thing".
