Jedd Fisch has found his next defensive coordinator, plucking him from the staff of a Pac-12 rival.
Arizona has hired Johnny Nansen as the successor to Don Brown, who left after one season to become head coach at UMass.
Nansen, 47, spent the last two years as defensive line coach at UCLA, helping the Bruins lead the Pac-12 in run defense at 124.25 rushing yards allowed per game. Arizona ran for 122 yards and 2.9 yards per carry against UCLA in a 34-16 home loss in October.
UCLA was the latest Pac-12 team that Nansen worked for.
