Ankron accepted a football scholarship to play for Texas Christian University under head coach Jim Wacker.
In 1985, he started the first 4 games at quarterback, but was lost for the year after tearing ligaments in his left ankle during the 0-41 loss against the University of Arkansas.
Ankrom was selected by the Dallas Cowboys in the 12th round (308th overall) of the 1989 NFL draft,[4] with the intention of using him as a wide receiver and kickoff returner.
On August 26, he injured his left knee while playing an exhibition game against the Denver Broncos, which became an injury that eventually would end his career.
In 1990 he was moved to safety, but suffered a season ending left knee injury in preseason and was placed on the injured reserve list on August 26.
