Chip Ganassi Racing has fired Kyle Larson after the driver was caught using a racial slur during a live-streamed virtual racing event Sunday night.
The team on Monday suspended Larson without pay, but Tuesday issued a statement saying it was "ending its relationship" with Larson, who was in the final year of his contract.
Larson was heard saying "you can't hear me? Hey, n----r" while chatting to other participants during the race.
Major sponsors of Larson's #42 car, McDonald's, Credit One and Clover had previously announced they were severing ties with the 27-year-old.
Larson has also been suspended from the NASCAR series and will need to go through sensitivity training before reinstatement is possible.
