The NASCAR Cup Series ran a single practice session at Chicagoland Speedway on Friday evening in preparation for the upcoming eero 400 on Sunday evening.
The 38-car field was split into two groups for practice.
Below you will find key notes from the practice session as well as the practice speeds for all drivers.
Important Practice Notes
Erik Jones - There was some damage found underneath Erik Jones' No. 43 Toyota. The team wasn't quite sure where this happened, but they know they hit something. If they need to repair it before the race on Sunday, Jones will have to start from the rear.
Well, we hit something somewhere during practice and lost time on track, but it’s still awesome to be back at @ChicagolndSpdwy pic.twitter.com/TbwhSvzPGW

Christopher Bell - The cast is off for Christopher Bell this weekend, and he simply has a splint on his wrist. There is no standby driver for the No. 20 Toyota this weekend so we can expect Bell to race the entire event.
