Las Vegas coach Jon Gruden said Wednesday the team addressed recent reports that multiple Raiders players were not wearing face masks at a recent charity event organized by tight end Darren Waller.
The event, which took place in Henderson, Nev., was hosted by The Darren Waller Foundation with the goal to raise money to help young people dealing with drug and alcohol addiction.
In addition to Carr and Witten, quarterback Nathan Peterman, tight ends Foster Moreau and Derek Carrier, wide receivers Zay Jones and Hunter Renfrow, and cornerback Nevin Lawson were in attendance, per ESPN.
"I'll just say this: We've done a good job," Gruden said, per ESPN. "We've done an excellent job. Last night, it was addressed with our players. They walked in with their masks on; there was an event. Photos, though, show players without masks upon arrival. No one's talked about (the event); He's raised over $300,000 for a great cause. I appreciate our players being there in support of him. But you're right. They may have let their dauber down a little bit by taking their masks off during the event. But it's been addressed and that's the best I can tell you."
Carr also said Wednesday "we had a few moments where we slipped up" during the event and took off their masks.
"We weren't perfect, but we were trying our best," Carr said. "We weren't trying to be careless or reckless."
Carr added: "We addressed it in-house. We admit we should have kept the masks on."
Raiders owner Mark Davis said Tuesday the team was investigating the news of several players not wearing face masks
"Guys have to be more stringent in fighting the virus," Davis told ESPN on Tuesday. "It's still our toughest opponent."
DragonRidge Country Club was fined $2,000 on Tuesday for violations of state COVID-19 regulations.
Davis told ESPN he was unhappy that the news of players not wearing masks overshadowed the charitable nature of the event.
The Raiders host the Bills on Sunday and Buffalo head coach Sean McDermott was asked if he had any concern over Las Vegas players not wearing masks.
"What we try to do is control what we can control from our end," McDermott said, per ESPN. "Got a lot of respect for coach Gruden and I'm sure they're on top of it over there."
This is not the first instance of members of the Raiders violating COVID-19 guidelines. Gruden was fined $100,000 -- and the team was docked an additional $250,000 -- for failure to follow the league's face-covering protocol during the Raiders' Week 2 win over the New Orleans Saints.
The NFL sent a memo to teams Wednesday stressing the need to follow COVID-19 guidelines on gamedays and stated that failure to do so could result in suspension and/or loss of draft picks.
