A day after losing to Stanford in the Pac-12 Conference title game to Stanford, USC Coach Clay Helton is shaking up his staff.
Keith Heyward, defensive backs coach for the last two seasons, said Helton told him Sunday that he would not return.
Asked if other coaches had also been informed they would not be back, Heyward said he did not want to comment on the situation of others.
But other people close to the situation said defensive coordinator Justin Wilcox and defensive line coach Chris Wilson were let go and receivers coach Tee Martin and linebackers coach Peter Sirmon were retained. USC plays Wisconsin in the Holiday Bowl on Dec. 30.
Heyward, who worked under former coach Steve Sarkisian at Washington before coming with him to USC, said Helton met with him to deliver the news. He said he was surprised.
"I was told it was nothing other than they wanted to go in another direction," Heyward said. "This is the business.
"Coach Helton has a vision and I respect that. I wish him well and USC well."
