NASCAR released a statement Sunday evening confirming that a noose was found in the garage area of the #43 car at Talladega Superspeedway.
The #43 car is driven by Bubba Wallace, the only African-American driver in the Cup Series.
Wallace has been outspoken in the wake of social justice protests, driving a car with a 'Black Lives Matter' paint scheme at a recent race.
Wallace also led the push to have the Confederate flag banned from NASCAR events.
"Late this afternoon, NASCAR was made aware that a noose was found in the garage stall of the 43 team.
We are angry and outraged, and cannot state strongly enough how seriously we take this heinous act.
The NASCAR Cup Series race at Talladega was postponed until Monday because of weather. »
