West Texas A&M football coach Ronnie Jones resigned Tuesday after a university investigation found he was operating a marketing business from his school office.
Athletics Director Ed Harris said in a statement that Jones used state and school resources for personal gain, "taking advantage of West Texas A&M property, facilities, funds, information technology resources, equipment, supplies, services and employee time."
No one answered Tuesday evening at an Amarillo telephone number for Jones, a former Buffalo Bills special teams coach who was suspended with pay last week.
Harris said Jones, who compiled a 5-27 record in three seasons with the Division II school, abused his authority, exerting undue influence on student-athletes and employees by soliciting memberships in his marketing venture.
Jones was a Bills assistant in 2000 under head coach Wade Phillips.
