Misdemeanor disorderly conduct charges against Ohio State cornerback Bradley Roby were dropped four days before the pretrial conference.
The All-American previously had a misdemeanor reduced to less serious charge.
The Columbus Dispatch first reported charges were dropped.
The charges stemmed from an incident on July 21 outside a bar in Bloomington, Ind., where Roby was accused of striking a security guard.
Roby has not missed any practices while police and Ohio State officials have investigated the incident, but he wasn't listed as a starter for the regular-season opener.
Buckeyes coach Urban Meyer said he is waiting for the investigation to conclude before deciding what, if any, punishment he will mete out. Meyer has indicated a suspension was likely, but that was beforethe charges were changed.
Roby had been projected as a first-round pick in last year's draft but came back to Columbus to help the Buckeyes build on their perfect 2012 season -- a season where Ohio State was ineligible for a bowl bid.
In two seasons with the Buckeyes, Roby has started all 25 games. In 2012, he compiled 62 tackles, 17 passes broken up and two interceptions.
Roby still has a pretrial conference slated for Aug. 26.
