An 18-year-old man from Bourbonnais, Illinois was cut by a boat propeller while tubing on Lake Maxinkuckee around 5 p.m. Wednesday.

According to the Marshall County Sheriff's Department, one of their boats was on patrol when it was approached by a boat.

The operator of the boat told officers he had an injured passenger.

When the operator tried to shut the boat off, he accidentally bumped the throttle.

Walker went under the boat and was cut by the propeller.

He was taken by ambulance to St. Joseph's Hospital with serious injuries. The injuries are not believed to be life-threatening.
