Harrison, 23, entered a not guilty plea during his arraignment Friday morning in Washington County Circuit Court.
The senior pleaded not guilty to possession of a controlled substance, two counts of possession, speeding, driving on a restricted license, not wearing a seat belt and failure to appear.
His trial is set for Nov. 20, three days before Arkansas faces second-ranked LSU in Baton Rouge in the regular-season finale.
Harrison was suspended for the Sept. 1 season opener against Troy University following his arrest, and he was demoted to a backup role.
The Little Rock native made his first start of the season in last Saturday's 42-29 loss to No. 14 Kentucky, but he recorded only one tackle at defensive end.
Harrison will serve as a backup defensive tackle in tonight's 6 p.m. game against North Texas in Reynolds Razorback Stadium.
