Two-time Cup champion Kyle Busch was hospitalized with a severe, undisclosed illness on Thursday, May 21, 2026, and will miss the NASCAR Craftsman Truck Series race on Friday and the Coca-Cola 600 on Sunday at Charlotte Motor Speedway.

Busch entered 2026 with the No. 8 Chevrolet for RCR, posting two top-10s in 12 races and sitting 24th in points. A recent crew-chief change paired him with Andy Street, after which the team earned two top-10s in three starts. His last Cup race absence was in 2015 due to a broken leg.

The central figures are Kyle Busch, his family, Richard Childress Racing, and Austin Hill, RCR’s O’Reilly Series driver who will substitute in the Cup race. Busch was also slated to drive the No. 7 Chevrolet Silverado for Spire Motorsports in the Truck Series.

Busch holds 63 Cup wins, 397 consecutive starts, and is 24th in points after 12 races with two top-10s this season. Austin Hill has 17 Cup starts, one top-10 (2025 Chicago Street Race), and is seventh in O’Reilly points with a Daytona win and recent P5 at Dover.

Busch’s absence ends a 397-race streak, the longest in modern Cup history, and removes a potential points source ahead of the playoffs. RCR may request a waiver to keep him Chase-eligible. The driver change also alters the competitive field for the 600-mile event.

The Busch family posted a notice citing a severe illness, treatment and a request for privacy. Richard Childress Racing released a statement stressing that Busch’s health is top priority, that full resources are being provided, that the No. 8 Chevrolet will be ready for his return, and thanking Austin Hill for stepping in.

RCR is expected to file a waiver request with NASCAR to preserve Busch’s playoff eligibility. The team will keep the No. 8 Chevrolet prepared, and Busch’s family has not announced a timeline for his return.
