On Saturday at Central Florida, Mizzou freshman receiver Dorial Green-Beckham's long-anticipated breakout moment arrived with his 80-yard touchdown reception in MU's 21-16 victory.

The play seemed to signal plenty more immediately ahead for the heralded Green-Beckham, the consensus top recruit in the nation.

"I think it would be wise to get him the ball as much as we can," MU coach Gary Pinkel said Wednesday during the Southeastern Conference media teleconference.

But Green-Beckham won't touch the ball, or even step on the field, on Saturday when Mizzou plays host to Vanderbilt in pursuit of its first league win as a member of the SEC.

Only hours after Pinkel spoke, Green-Beckham's forward progress took an abrupt step backward when he was one of three Tigers arrested by University of Missouri police on suspicion of possession of less than 35 grams of marijuana.

Police patrolling a lot near Faurot Field made the bust when they smelled marijuana coming from a car, a 2004 Lincoln Navigator registered to Green-Beckham.

"We're aware of the incident and have addressed it," MU athletics spokesman Chad Moller said via e-mail. "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."

Also arrested and facing the same punishment were Tiger freshman receiver Levi Copelin and freshman linebacker Torey Boozer.

Also suspended for the game are freshman defensive lineman Harold Brantley and freshman tight end Brandon Holifield.

They were in the car but were not arrested because they were not in possession of marijuana, Capt. Brian Weimer of the MU police said.

The four implicated with Green-Beckham are not on MU's primary depth chart and are expected to be redshirted this season.

In the process of learning Mizzou's intricate offense, Green-Beckham had made little impact before Saturday. He had just six catches for 48 yards before his 80-yard catch-and-dash, after which he calmly dropped the ball in the end zone.

"I was just really patient," he said Monday. "I knew my moment was going to come anytime soon."

Offensive coordinator David Yost said Monday it likely was "a relief" for the much-heralded DGB and added, "We've got to get him the ball more."

But that will have to wait at least another week in the wake of the arrest at about 11:40 p.m. Wednesday.

According to Weimer, university police had been on routine patrol in Lot G south of the stadium.

"We check the lots to make sure no vehicles are broken into," he said, adding that the MU police make more than 100 marijuana arrests a year and are "very aware" that people occasionally smoke dope in parked vehicles.

When the officer on patrol came across the white Navigator, Weimer said, he detected the odor of pot and determined that three of the occupants had been in possession of less than 35 grams.

The car is registered to Green-Beckham, Weimer said, and he was in the driver's seat but the engine was not running.

Weimer said the possession will be treated as a city municipal matter, and it's likely the penalty would be a fine for first-time offenders. He declined to release the arrest report, saying it would be held as part of the investigation until the matter goes to court.
