The website reports that wide receivers coach Derek Sage has accepted a similar position as part of Chip Kelly's inaugural staff at UCLA.
Washington State ranked first among Pac-12 teams in passing yards with a 366.8 yards per game average in 2017.
Sage joined Wazzu last offseason and had previously spent three seasons at Toledo, as well as Wyoming for four years.
The assistant will join linebackers coach Roy Manning, who accepted the special teams coordinator position with the Bruins last month.
Former defensive coordinator Alex Grinch (to Ohio State), running backs coach Jim Mastro (to Oregon), offensive line coach Clay McGuire (to Texas Tech) and strength coach Jason Loscalzo (to the Chicago Bears) were the other departures this offseason.
Washington State finished the 2017 season with a 9-4 (6-3 Pac-12) overall record, which ranked third in the Pac-12 North.
