NASCAR Cup Series points leader William Byron crashed during practice for this weekend’s street-course race in Chicago, damaging the left-rear corner of his No. 24 Chevrolet after losing traction in Turn 10. Byron had been atop the speed charts when the impact occurred, and preliminary assessments from the team indicated a broken left-rear toe link and related suspension damage. The incident jeopardises the clean, problem-free outing Byron said he needed as his regular-season points advantage has recently narrowed.
The No. 24 gets into the wall! @WilliamByron was at the top of the speed charts at the time of this incident. https://t.co/hoNMOju9J4
William Byron was fastest in Group 1 Chicago practice but also broke traction in Turn 10 and slapped the wall with his left rear Likely some toe damage for the points leader
William Byron got loose and hit the wall with the left rear of his car. Would guess he has suspension damage.
