During a Lap 111 restart, the No. 4 of Christopher Bell tipped the back ofKyle Busch Motorsports teammate Daniel Suarez's No. 51 entry, causing a chain reaction to bring out the caution at Atlanta Motor Speedway.
Suarez's truck immediately got into race leader Matt Crafton's No. 88 Toyota, which immediately went spinning on the 1.54-mile track.
NASCAR then brought out the red flag on Lap 112 while cleanup began.
Both Crafton's and Suarez's Toyotas were wheeled to the garage, done for the day with significant damage. Both drivers were evaluated and released from the infield care center.
