Iowa has hired Minnesota Vikings assistant Chris White to coach running backs and coordinate special teams.

Head coach Kirk Ferentz announced Friday that White would replace Lester Erb, who left after 13 seasons at Iowa. White had been with the Vikings for four seasons after a long career at Syracuse.

White's hiring comes as Ferentz completes the second shake up on his staff in as many years. Iowa's 4-8 record last year, including a six-game losing streak to end the season, was its worst since 2000. Ferentz's program has struggled since its victory in the 2010 Orange Bowl.

Ferentz recently announced former Colorado assistant Bobby Kennedy would coach the wide receivers and former Virginia assistant Jim Reid would help with defense. Ferentz hired new offensive and defensive coordinators last year.
