A criminal complaint says Trooper Doug Rauenhorst and his partner pulled over a Jeep for a traffic violation last Thursday in Faribault County and suspected the driver and passenger from Milwaukee were transporting drugs.
The complaint says Rauenhorst was partly in the vehicle when the driver accelerated and the passenger punched the trooper in an attempt to force him out of the Jeep.
Prosecutors say Rauenhorst was dragged along Interstate 90 before he fell out of the moving Jeep. He was treated at an Albert Lea hospital for his injuries.
Two men from Wisconsin, Anthony Hector Enriquez, 28, and Montrell Antonio Smith, 29, were arrested in Albert Lea and booked into the Faribault County Jail for felony assault and possession of a controlled substance.
The injured trooper has been with the State Patrol for 22 years. He was released Friday from the hospital.
