Manion was crew chief on the No. 9 beginning at the spring Kansas race. He replaced Drew Blickensderfer, who was moved to director of research and development.
Motorsport reports Blickensderfer is a candidate to be Scott’s crew chief.
In the absence of a crew chief, Trent Owens, the crew chief on the No. 43 of Aric Almirola, will lead the No. 9 team at the Goodyear tire test at Homestead-Miami Speedway on Monday.
