Glenn Spencer is out as the defensive coordinator at Oklahoma State, multiple sources told Pistols Firing on Thursday.
Spencer alerted the coaching staff of the personnel change via text message on Thursday. He had been the head of the defense since being promoted from within in 2013.
It is believed that Spencer was let go earlier in the week and that he was at the AFCA Annual Convention this week in North Carolina.
Spencer’s defense ranked No. 58 in the country in points per drive given up in 2017.
