Bubba Wallace, the only Black driver in NASCAR's top circuit, says he is "incredibly saddened" after a noose was found in his team's garage at Talladega Superspeedway in Alabama on Sunday.
"Today's despicable act of racism and hatred leaves me incredibly saddened and serves as a painful reminder of how much further we have to go as a society and how persistent we must be in the fight against racism," Wallace said in a statement on Twitter.
But he said he won't be deterred by the "reprehensible actions of those who seek to spread hate."
"This will not break me, I will not give in nor will I back down. I will continue to proudly stand for what I believe in."
Wallace was instrumental in calling for the auto racing company to ban the display of the Confederate flag at its events. He raced with a Black Lives Matter paint scheme on his car during a NASCAR event last week.
