The two were discussing an on track incident where Gragson hit the wall when things started to escalate quickly when Gragson grabbed Chastain's firesuit. Chastain told Gragson to stop but Gragson didn't and Chastain responded by throwing a punch at Gragson that connected and the two got into a scuffle on pit road. Gragson tried to punch Chastain back but was held back by security and the two were eventually separated on pit road.^[12]
