LOS ANGELES — On Friday afternoon, USC announced the resignation of Mike Bohn as the school’s Athletic Director.

The move comes as a shocker, given that Bohn held the job for less than four years and was incredibly popular among USC fans. According to reports, health issues were a factor in the decision of Bohn—who is 62—to resign.

Bohn arrived at USC in November of 2019 after previously serving as the AD at Idaho, San Diego State, Colorado, and Cincinnati. He replaced the embattled Lynn Swann, who resigned following the Varsity Blues college admissions scandal.

During his time as the Trojans’ Athletic Director, Bohn made numerous changes to the department, including significantly increasing financial investment in USC’s athletic programs. This was headlined by the marquee hire of Lincoln Riley as USC’s head football coach in November 2021.

Last summer, Bohn made another landmark move, with USC’s departure from the Pac-12 for the Big Ten Conference. The Trojans are set to join the Big Ten next year.

In a statement to the university community, USC President Carol Folt noted that, “over the last four years, the USC athletics department has transformed into a national powerhouse. In our singular pursuit of excellence, I am committed to ensuring we have the right leadership in place to achieve our goals. As part of that commitment and as we prepare to move to the Big Ten, we conducted a thorough review of the athletics department, including its operations, culture, and strategy. Having built a strong foundation over the last few years, now is the time for new direction grounded in our values and in expertise needed to fulfill our aspirational vision for Trojan athletics.”

Folt added, “I thank Mike for his contributions to our athletics department during a time of rapid transformation and growth. We will be announcing a transition team comprising both internal and external leaders in the coming days and will launch a national search for a new director of athletics shortly.”

Whoever is tapped to fill Bohn’s role will have big shoes to fill, as he left a tremendous legacy during his short time at USC that will last for decades. Said replacement will be tasked with leading the Trojans as they enter a new era of USC Athletics in the Big Ten.
