Nick Rolovich, who lost his job as Washington State’s head coach by refusing to be vaccinated against COVID-19, was hired by Cal as a senior offensive assistant on Friday.Rolovich led the Huskies to a 1-3 record in the abbreviated 2020 season, then a 4-3 mark in 2021 before he was fired when he wouldn’t adhere to the state of Washington’s vaccine mandates for state employees.Rolovich contended he had a religious objection to the vaccine, but the university rejected his explanation. He subsequently filed a lawsuit for wrongful termination, and the case is still pending.Cal’s school policy requires students, faculty, and staff to be vaccinated or opt out by submitting a written statement.Rolovich, 45, joined the Cougars after a stint as coach at Hawaii from 2016-19, where he produced a 28-27 record and led the Rainbow Warriors to three bowl games.
