Frank Shannon, Oklahoma's starting middle linebacker and leading tackler last season, is facing a sexual assault allegation, according to a Title IX sexual misconduct allegation report obtained by the Oklahoman.

Shannon, a junior linebacker, did not take part in last Saturday's spring football game at OU. When inquired about the reason why, OU coach Bob Stoops said, "Frank right now is working some personal issues, so we'll wait and see on that."

Title IX laws require that public schools that receive federal funding investigate sexual assault cases and act in accordance, promptly and equitably, with its findings. Any school that does not fulfill responsibilities under Title IX can be fined or be denied further institutional access to federal funds.

Shannon has been accused of violating the University of Oklahoma's Sexual Misconduct, Discrimination and Harrassment Policy, the Oklahoman reported.

Norman Police confirmed they are investigating the incident, according to the newspaper.

OU athletics department spokesperson Pete Moris told the Tulsa World on Wednesday night that the school is declining comment.

The Oklahoman reported the accuser alleged Shannon offered to give her a ride, but needed to drop friends off near his apartment. Shannon allegedly took the woman into his bedroom and attempted to have sex with her.
