There’s a late-season change happening at Kaulig Racing.

In a statement released on Wednesday, the organization confirmed that Mike Cook, the team’s Technical Director, will serve as the interim shot-caller for Ty Dillon and the No. 10 Chevrolet Camaro ZL1 for the final two NASCAR Cup Series events of 2026 – at Martinsville Speedway and Homestead-Miami Speedway.

The statement reads… “Kaulig Racing announced today that Technical Director Mike Cook will serve as interim Crew Chief for Ty Dillon’s No. 10 NASCAR Cup Series car for the final two races of the 2026 season, replacing Andrew Dickeson.”

Cook, a native of Tracy’s Landing, Maryland, joined forces with Kaulig Racing prior to the start of the 2025 NASCAR Cup Series campaign as the team’s first-ever Technical Director. For more than a decade, Cook spent time in the NASCAR Cup Series as a Lead Engineer for Stewart-Haas Racing, working with drivers Kurt Busch, Aric Almirola, and Chase Briscoe.

Surprisingly, though, despite his long tenure in the NASCAR Cup Series, Sunday’s XFINITY 500 at Martinsville Speedway will mark just his second start as a crew chief at NASCAR’s top-level. In 2021, Cook filled in as shot-caller for the No. 14 Ford Mustang with Chase Briscoe at Atlanta Motor Speedway, where Briscoe finished 15th.

Cook replaces Andrew Dickeson as crew chief of the No. 10 Chevrolet Camaro.

Dickeson has served as a crew chief a total of 78 times in the NASCAR Cup Series, earning three top-10 finishes – one with Ty Dillon in 2025 and two with AJ Allmendinger in 2024. After spending the last two years – and change – with Kaulig, Dickeson has been bounced out of the crew chief position.

The move comes as Ty Dillon sits 33rd in NASCAR Cup Series point standings with just two races remaining in the season, sitting on an average finish of 26.0 and three laps led, both marks lower than his first full-time campaign with Kaulig in 2025.
