Keselowski shot up the track and into Kurt Busch, sending the field scrambling.
Also involved were Denny Hamlin, Kevin Harvick, Ty Dillon, Erik Jones, Joey Logano, Ryan Blaney, Kyle Larson, Alex Bowman, Bubba Wallace, Austin Dillon, Kasey Kahne, Jamie McMurray, Clint Bowyer, Daniel Suarez, Paul Menard, Jimmie Johnson, Matt DiBenedetto, Jeffrey Earnahrdt, Corey LaJoie, Michael McDowell, Ross Chastain and Aric Almirola.
Kurt Busch and Logano were eliminated.
Keselowski was upset with how Byron was racing him.
“It was just a bad block,” Keselowski told NBC Sports and ESPN. “There are times you can make a block, there are times you can’t. When you got a guy with a big enough run and you can’t throw a block. I made the mistake of lifted instead of wrecking him and that’s my fault. I take the blame
“You got a list of drivers that are making moves that are unqualified to make and it causes big wrecks. That was one of those. It was my fault because I lifted. I should have wrecked him and sent a message to the whole field. So we’ll wait until Talladega and every one of those rookie drivers or guys that don’t know what the hell they are doing we’ll drive through them and wreck them until they stop blocking us and we don’t have this problem no more.”
Said Hamlin: “I’m not sure but somebody probably wrecked somebody. Usually the person that starts it doesn’t get wrecked. (Keselowski) was sideways in front. Yeah, the 2 got wrecked and so did everybody else.”
Said Logano: “Felt like the longest crash ever.”
