Dan Guerrero will retire as UCLA athletic director next July, ending a 17-year tenure that is the second-longest among current ADs in the Power Five.
Guerrero announced Thursday that he made the decision to step down in 2020 after successfully fighting a previously undisclosed cancer. He credited UCLA's medical team with helping him beat the disease and said his future prognosis is "excellent."
He said he and his wife recently welcomed their second granddaughter and spending time with his family is "incredibly important."
