Days after North Carolina placed the highest-paid general manager in college football, Michael Lombardi, on paid administrative leave, UNC head coach Bill Belichick largely avoided the topic in a news conference before the Tar Heels’ first practice of preseason camp.Asked how UNC is dealing with Lombardi’s absence, Belichick said: “We are working through some things. We’re at a particular time of year now where there are certain things that are in play and certain things that aren’t in play. … We’re taking it day by day. And, you know, working through the things that are on the table now.”Earlier Thursday, the university said in a statement: “As a result of concerns behind allegations that led to the personnel action regarding Michael Lombardi announced on July 27, the University of North Carolina at Chapel Hill, through its Office of University Counsel, is in the process of investigating this matter. Because this involves confidential personnel issues, the University will not comment on the nature of the allegations or discuss personnel information.”Lombardi’s leave is connected to a human resources complaint, three people briefed on the matter, who spoke on the condition of anonymity because they are not authorized to comment publicly, told The Athletic earlier this week. According to the North Carolina handbook, administrative leave “should not exceed 30 days,” meaning a decision on Lombardi’s future should come before the Tar Heels’ Aug. 29 season opener against TCU in Dublin.
