MU Police Department spokesman Brian Weimer said the three were found in a white Lincoln Navigator in Lot G, just south of Memorial Stadium.
“The officer noticed the individuals sitting in a car and went up and made contact,” Weimer said. “The officer observed the odor of marijuana. Through the investigation, the officer made the arrest of three individuals.”
Weimer said there were two others in the vehicle at the time, but the investigation determined they had nothing to do with the marijuana and they were released.
Green-Beckham, Boozer and Copelin were taken to the police department for processing and released on signature summons, Weimer said.
In a statement, team spokesman Chad Moller said the three will be suspended from the football program for one game.
“We’re aware of the incident and have addressed it,” he said in the statement. “All individuals involved have been immediately suspended from the program for one game. All other disciplinary measures will be handled internally, and there will be no further comment.”
Green-Beckham had his first collegiate touchdown last Saturday on an 80-yard pass in the team’s 21-16 win over Central Florida.
