Marshall defensive coordinator Chris Rippon has resigned.
Marshall announced the resignation Saturday, a day after the Thundering Herd (5-7) finished the season with a 65-59 loss in double overtime at East Carolina.
Marshall allowed an average of 43 points per game this season.
Rippon spent three seasons at Marshall. He also had assistant coaching roles at Rutgers, Mississippi and Syracuse.
“I would like to thank Chris for all of his service to our program,” said Marshall head football coach Doc Holliday. “We wish him and his family the best.”
