California has hired Art Kaufman to lead its much-maligned defense, according to a source.

The team was informed Wednesday of the hiring of Kaufman, who led Cincinnati's defense last season. Kaufman was with Tommy Tuberville at Texas Tech in 2012 and Cincinnati in 2013 before being let go this offseason.

FootballScoop.com reported the news Wednesday afternoon.

Cal needs a defensive overhaul after ranking 124th nationally in total defense, allowing 529.6 yards per game.
