1:20 p.m.:
In the practice round of the Cup Series, the same wall that caused an earlier crash for Sheldon Creed proved to be just as hazardous to Ricky Stenhouse Jr.
2:20 p.m.
Chase Elliott is now out of the Cup Series qualifier after a hard crash into the course's difficult ninth turn.
2:30 p.m.
Longtime NASCAR driver Kevin Harvick has crashed out of qualifying after not being able to cleanly cut a turn and colliding with a course barrier.
2:55 p.m.
The Cup Series qualifying race has wrapped up, with Denny Hamlin winning pole position for Sunday afternoon's Cup Series race.
With both Xfinity Series and Cup Series drivers now acclimating themselves to the Chicago Street Course, calculated caution has appeared to be the approach thus far.
Drivers have taken advantage of the course's wide turns and straightaways for passing opportunities, while braking timing has proven to be incredibly crucial.
Although drivers have avoided any major vehicle-on-vehicle collisions, several crashes into the course's barriers have occurred, particularly on the course's challenging eighth and ninth turns.
The half oval-shaped turns have proven to require pinpoint precision to get out unscathed, also causing drivers who haven't crashed to slide when coming out of the turn.
