Korbin Forrister's frustration overflowed at Phoenix International Raceway after his No. 08 Chevrolet spun in the early laps of the Lucas Oil 150.
On his way to the ambulance after spinning into the wall on Lap 16, Forrister threw his HANS device toward Timmy Hill's No. 94 Chevrolet.
Forrister, crew chief Christopher Long and the No. 08 team's spotter were called to the NASCAR hauler for a meeting.
After the race, Hill tweeted an apology to Forrister, who also apologized for his reaction.
