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.
