A 2019 Western Star semi, driven by 42-year-old Thomas Swor of Carleton, Michigan, was traveling westbound on US 33 when it lost a wheel.

A motorcycle driven by 26-year-old Treven Marchal of West Liberty then struck the wheel, causing him to lose control.
Marchal was wearing a helmet but was ejected from the motorcycle.
He suffered serious injuries and was transported to Mary Rutan Hospital by Perry Township EMS.
Swor was cited for operating an unsafe vehicle.
The semi and the Dodge were towed from the scene.
