Christopher Bell completed a sweep of the Round of 16 for Joe Gibbs Racing in the 500-lap event at Bristol Motor Speedway, which each of the team's three playoff drivers winning a race this round.

It was Bell's fourth win of the year, but his first since Phoenix Raceway in early March. It also follows a race at Gateway when he expressed frustration with his team for not being able to get victories despite race-winning cars.

While he joins 11 other drivers in the Round of 12, after climbing from the No. 20 Joe Gibbs Racing Toyota victorious on Saturday night, Bell spared a moment in his post-race interview to pay tribute to conservative media personality Charlie Kirk.

“Most importantly, this week has obviously been a very tough week, and there's a lot on our mind,” said Bell in his front stretch interview with USA Network. “This one is for Charlie.”

Kirk, aged 31, was shot and killed on Tuesday while holding an event at the Utah Valley University.

Throughout the weekend, there were various other tributes as Bristol Motor Speedway put up a dedication in remembrance of Kirk on the big screen at the half-mile short track, while all of the Richard Childress Racing cars carried tribute decals.
