On Wednesday, Knox County district attorney general Charme Allen announced Pearson will not face rape charges after being named a suspect in a three-month investigation.
Pearson, 23, was accused of rape in April by a fellow Tennessee student and subsequently suspended by both the football team and the university.
After reviewing the investigation, Allen determined there was insufficient evidence to sustain a criminal prosecution.
Pearson is the Volunteers' second-leading returning receiver. In 11 games last season, he recorded 393 receiving yards on 38 catches with five touchdowns.
Tennessee opens its 2015 season on Sept. 5 against Bowling Green at Nissan Stadium in Nashville, Tenn.
