Mel Tucker is currently suspended without pay as of Sunday evening with Michigan State AD Alan Haller announcing the details at a press conference. Since then, more details about the timeline of events and when MSU leadership learned the details of the investigation have filtered out.

According to ESPN’s Dan Murphy, an MSU spokeswoman confirmed Sunday evening that Spartan leadership knew of a complaint filed against Tucker by Brenda Tracy in late December. However, university leaders — including AD Haller — did not know the details of the complaint until Saturday night.

Murphy also cited Title IX and sexual misconduct experts who said that is the proper, trauma-informed protocol for handling this form of complaint. Michigan State leadership — Tucker’s bosses — should not have known about the details during an open case per Murphy.

Murphy also cited the MSU spokeswoman for revealing the official reason for Tucker’s suspension was “unprofessional behavior and not living up to the core values of the department and university.” Prior to this weekend, the university did not know Tucker had admitted to any sexual encounters.
