Byron suffered a mechanical failure and finished 40th in the Grant Park 165 NASCAR Cup Series race at the Chicago Street Course on Sunday afternoon.
ANALYSIS
The day turned almost immediately bad for Byron from the drop of the green flag. He radioed in to his team that he was having problems on lap 1. Byron would bring the No. 24 Chevrolet to pit road with a clutch issue. The team would take a look and see if the problem could be fixed but it was beyond an easy repair. Byron would be retired for the day with his second DNF of the season.
