Dale Earnhardt Junior will not compete in Sunday’s Sprint Cup Series race in New Hampshire, suffering from concussion-like symptoms. Following accidents last month at Michigan International Speedway and earlier this month at Daytona International Speedway, doctors evaluated Earnhardt this week in Charlotte and did not clear him to race. Alex Bowman will drive the Number-88 Hendrick Motorsports Chevrolet in the New Hampshire 301. The 23-year-old from Tucson, Arizona, is running a limited X-FINITY Series schedule for Junior Motorsports this year with a best finish of third place in four starts, that coming in mid-May at Dover. A timetable for Earnhardt’s return has not been established.
