BRISTOL, Tenn. -- Joey Logano led the final seven laps Saturday night at Bristol Motor Speedway after seizing the lead from Carson Hocevar, who overshadowed the winner despite finishing third.
Hocevar, a brash 23-year-old who has earned the ire of veterans with his aggressive driving, traded punches in the pits with an aggrieved Ryan Blaney after the former wrecked the latter's car from behind.
Hocevar stopped his car after finishing third and was greeted by a shove from Blaney. Hocevar responded by swinging twice at Blaney, who fell to the pavement, got up and threw a punch at Hocevar before they were separated by their crews.
The incident occurred with 41 laps left, when Hocevar clipped Blaney's left rear bumper, causing Blaney's car to spin out.
Logano started from the pole position and led 93 laps to move into third place in the points standings.
Kyle Larson finished second to move into the Chase lead by a point over Denny Hamlin.
Christopher Bell was fourth, followed by Ty Gibbs, who led 120 laps before finishing fifth.
Gibbs was driving a No. 54 Toyota that sported a paint scheme honoring the late Kyle Busch, who had a record 23 wins in NASCAR national series at Bristol.
It was among multiple tributes to the Richard Childress Racing driver who died in May.
Fans waved yellow towels on the 18th lap in honor of Busch, who won two Cup Series championships in the No. 18 Toyota. His widow, Samantha, addressed the crowd before the race.
"Bristol was always so special to Kyle," Samantha Busch said. "He loved racing under the lights, the energy of this place, and most of all, the fans. For 20 years, this sport was our life. It's where we raised our babies and made some of our very best memories. I never imagined we'd be standing here without him. But looking out at all of you reminds me that we aren't walking this alone."
