Iowa RB Greg Garmon

After saying in a Facebook post that he would arrive in Iowa City on Sunday, running back Greg Garmon still hasn’t shown, according to sources.

Garmon, a 6-1, 195-pound running back, hasn’t spoken to the media since being hit with misdemeanor charges of simple possession of marijuana and possession of drug paraphernalia after a June 7 traffic stop in his hometown of Erie, Pa. Garmon also has since deleted his Twitter account.

A preliminary hearing is scheduled for July 18.

Iowa coach Kirk Ferentz also hasn’t issued a statement since Garmon’s arrest. Iowa sports information director Steve Roe said Tuesday that the next time Ferentz is likely to be interviewed will be the Big Ten media days July 26-27.

Freshmen started showing up for summer workouts, which began the first week of June. Not all freshman are in Iowa City. These workouts aren’t mandatory. Iowa’s fall camp begins the first week of August.

Barkley Hill, an incoming freshman from Cedar Falls, has reported for workouts. Iowa ended spring practice sophomore Damon Bullock No. 1 on the depth chart followed by sophomore De’Andre Johnson and junior college walk-on Andre Dawson.

Jordan Canzeri has continued his rehab from a torn ACL suffered on the first day of spring practice. In October, he would be six months out of surgery, but he will likely redshirt and come back as a healthy sophomore in ’13.

Iowa has a need for running backs. Garmon was definitely in that mix.

“I think we have to have the approach that both those guys, if they can help us, will, just because of our numbers right now,” Ferentz said post-spring. “I’m pleased with the progress that Bullock and Johnson made during spring.  I think they improved pretty much each and every day and feel a lot better about what they’re doing now and where they’re at.

“But we’re going to need more than two guys, certainly, so if those two guys [Garmon and Hill] can help us, that would be a great thing.”
