NASCAR's Bubba Wallace is apologizing to Kyle Larson for forcefully shoving the former champ during an on-track altercation at the Las Vegas Motor Speedway on Sunday -- saying he simply lost his cool.
The quarrel happened during the NASCAR Cup Series race -- after Wallace intentionally crashed his Toyota into Larson's No. 5 Camaro ZL1 as retaliation for brushing him into the wall when the two drivers were side by side.
Wallace's rage continued after the cars finally came to a stop off the track .
