“Today is bittersweet for me and for my family, as UCLA has been a part of my life for more than 50 years,” Guerrero said in a statement, which said two of the reasons he had decided to retire included a recent battle with cancer and the birth of his second granddaughter.

“For these reasons, it is time for me to step aside and for UCLA Athletics to flourish under new leadership while I focus on my health and on my family,” he said in the statement.
