Martin Truex Jr. knows outsiders hear the infighting on his Joe Gibbs Racing team radio and assume it’s a sign of bigger troubles within the team.

“We talked right after the race; everything is fine,” Truex said. “It’s frustration. Heat of the moment. We talked Sunday night, Monday, and all week. Everything is fine. It’s just one of those things that happens.”

The former NASCAR Cup Series champion offered the reassurance Saturday at the Bristol dirt race. Truex said he and crew chief James Small, who went back and forth on the radio after the checkered flag last weekend at Richmond Raceway, have a great relationship, and sometimes frustration comes out.

“It’s part of what you do,” Truex said. “It’s intense competition.”
