Overview
- Busch, who radioed his team late Sunday at Watkins Glen, asked for Dr. William Heisel to meet him at his bus and said he would need a shot.
- He stayed in the car and finished eighth for his best result of 2026 after running as high as fifth.
- No official diagnosis was given, though the FS1 broadcast said he had dealt with a sinus cold during the week.
- His choice of the team bus over in-car help signaled the issue was manageable during the race and likely needed only post-race treatment.
- The moment comes in a difficult contract year for Busch, who has not won since June 2023 and recently switched to crew chief Andy Street at Richard Childress Racing.
