Seminoles teammates Chris Casher and Ronald Darby are the subjects of Tuesday's disciplinary hearing, which will deal with their actions the night Winston was accused of raping a female student in 2012.
Winston was not asked to testify at the hearing and is with the Florida State baseball team in North Carolina, attorney Tim Jansen told ESPN.com.
Casher and Darby could face expulsion if they are found in violation of Florida State's code of conduct related to the rape accusation against Winston.
According to police documents, Casher and Darby told authorities they witnessed Winston having sex with the alleged victim on Dec. 7, 2012 at an off-campus apartment. Casher later admitted to recording a cell phone video of the sexual encounter.
Police investigated the incident and state prosecutors decided not to pursue charges against Winston, citing a lack of evidence. A New York Times investigation published last month uncovered major flaws in the Tallahassee Police Department's investigation.
Winston, the reigning Heisman Trophy winner, said the sex with his accuser was consensual.
Florida State is one of 55 colleges and universities currently under investigation for how they handle sexual assault complaints.
More from the Wall Street Journal:
Casher and Darby haven't been charged with a crime. The hearing is part of an investigation the school is conducting into whether the two men's actions that night violated the university's code of conduct, which prohibits, among other things, conduct that invades a person's privacy or creates an intimidating, hostile, or offensive environment.SI.COM STAFF: The 100 things we’re most excited for in the 2014 college football season (Nos. 100-81)
