TEMPE, Ariz. -- Tyrann Mathieu wants the world to know his stance on racism -- feet first.
The Arizona Cardinals' safety will be wearing gold cleats with the phrase "Sideline Racism" on them to promote an organization called RISE, established in 2015 by Miami Dolphins owner Stephen Ross. RISE is a nonprofit that is "dedicated to harnessing the unifying power of sports to improve race relations and drive social progress."
Mathieu explained why he chose to promote a group that supports ending racism with the help of sports.
"For me personally, it's been a rocky year, been a lot of racial divide within our country," Mathieu said. "So for me it was important for me to wear something that symbolizes all of us coming together, all of us treating each other as equals.
"That's really my message so I think it's a good one."
His cleats are part of the NFL's "Cleats for a Cause" campaign. Players around the league are allowed to wear cleats adorned with a cause of their choice, whether it be a foundation, organization or charity, among other groups, that they either support or are involved in.
Mathieu was grateful the NFL, which typically has stringent uniform policies on game day, gave players an opportunity to show support for causes they're behind.
"That was big time," Mathieu said. "Kudos to the NFL for letting different guys wear different cleats to take advantage of whatever they believe in."
