Paul Wulff, fired as Washington State's football coach after last season, will join the San Francisco 49ers as an offensive assistant coach.

Paul Wulff, fired late in 2011 after a four-year stint as Washington State’s football coach, will be named this week to the position of senior offensive assistant with the San Francisco 49ers, a league source confirmed.

Wulff is joining an old Pac-10 adversary, 49ers coach Jim Harbaugh, whose Stanford teams met Wulff’s WSU clubs three times from 2008 through 2010.

Wulff’s duties with the 49ers are unknown. But his background is with the offensive line, where he played at WSU a generation ago and which he began coaching at Eastern Washington in 1993.

The move also brings Wulff, 9-40 at WSU, near to his northern California roots. He grew up in Davis, Calif., and went to high school there before attending WSU.
