Hoke referred to a statement released to select media Monday when asked about the timeline of Gibbons' disciplinary process. The coach cited privacy laws and university guidelines as reasons he could not elaborate.
"Michigan athletics has no influence over any part of a review of a potential violation of the university's student code of conduct -- not the process, the investigation or the timing of the resolution," Hoke said in the statement. "In general, while we may be aware of an ongoing proceeding, we always strive to balance transparency with privacy.
"Our usual approach is not to issue discipline related to a student's standing on the team before the university's process runs its course and the outcome has been determined. We will always respect the rights and confidentiality of the process and the parties involved. One way we do that is by not discussing the details of student disciplinary matters.
"So while I would like to be more forthcoming, I can't provide any details due to federal privacy laws and university policies."
The Michigan Daily, the university's independent student-run paper, reported last week that Gibbons was "permanently separated" from the university effective Dec. 20, 2013, due to a violation of the university's sexual misconduct policy as a result of a sexual assault allegation from November 2009.
