Sources close to the situation have confirmed that former San Francisco 49ers offensive coordinator Mike Johnson will join the UCLA offensive staff, though his role is undetermined with offensive coordinator Norm Chow’s future still in doubt with the Bruins.

UCLA officials say that a hire has still not been made, but Johnson was on UCLA’s campus on Tuesday and took a tour of the weight room, where he met several players who said their interaction with Johnson was brief. Chow, who reportedly has had talks with Utah to become its offensive coordinator, remains on the UCLA staff and continues to recruit for head coach Rick Neuheisel.

Johnson has extensive NFL experience as a wide receivers and quarterbacks coach, and he and Neuheisel coached together for the Baltimore Ravens in 2006-07. Johnson was quarterbacks coach for the Atlanta Falcons from 2003-05, working with current Philadelphia Eagles quarterback Mike Vick, and previously served as wide receivers coach and quarterbacks coach at Oregon State in the late 90s.

Chow, meanwhile, continues to dangle in the wind, though sources indicate a resolution could come soon.

Chow, who came to UCLA with much fanfare in 2008 but whose offenses have foundered in three straight seasons, had a two-year contract extension approved late last year, and UCLA would be on the hook for the full amount if Chow was fired.

While UCLA’s offensive staff appears to be taking shape, the Bruins remain without a defensive coordinator less than three weeks before signing day.
