Washington Redskins wide receiver DeSean Jackson wore cleats depicting yellow caution tape during Sunday's pregame workouts in an attempt to raise awareness about police-related violence.
Jackson told ESPN's Adam Schefter that he was not taking a stance against law enforcement.
"Today is the start of my attempts to be part of a solution and start dialogue about the senseless killings of both citizens and police," Jackson said in a statement to Schefter. "I have chosen to wear these cleats in pregame today to use my platform as a pro athlete to add to this discussion. This isn't meant to be any kind of protest against the good men and women in law enforcement in this country. I just to express my concern in a peaceful and productive way about the issues that are currently impacting our country."
According to USA Today, Jackson later decided to wear the cleats in the game against the Cleveland Browns.
That decision could result in a fine for violating the NFL's uniform policy. Sports Illustrated's Johnathan Jones reported that players are prohibited from wearing or displaying personal messages unless the message is approved in advance by the league office.
Regardless, the Washington Redskins said they supported Jackson's decision.
"We stand in support of both DeSean and the law enforcement community," the Redskins said in a statement to Schefter. "We have great respect for law enforcement and the sacrifices they make each and every day to protect and serve our communities. We continue to have open dialogue with our players about issues that are important to them and support their efforts to bring awareness to those issues when done in a responsible manner."
