Erik Jones must have felt he has this one in the bag.
He was leading much of the race when his teammate at Joe Gibbs Racing, Christopher Bell, slid underneath him, grabbed the lead, and went right in front of Jones.
Jones ended up running his No. 20 into the back of the No. 18, damaging his car, and Bell made it over the line first.
Here's what happened.
A battle for the win between teammates ended with them both hitting the wall!

A visibility upset Jones wasn't happy in his post race comments broadcast on NBC.
"It's not dirt racing, you know, he's not clear," Jones said. "I just can't stop on the top." He added, "I thought we were gonna race for the win and unfortunately it wasn't much of a race it was more of a wreck."
"It's not dirt racing."

"I never want to wreck anyone," Bell said. Then, he added, "I was clear. It's my first win. I'm sorry that Erik couldn't finish the race. But I'm just stoked."
"I was clear."
