The Austin Jackson era in Norman has come to an end before it even got started.

In mid-August, Oklahoma added Jackson’s name to its roster after the defensive back opted to transfer from Clemson earlier in the offseason. Less than a month later, Jackson announced on his personal Twitter account that he is retiring from football.

The player gave no specific reason for the decision.

Jackson actually began his collegiate playing career at East Tennessee State in 2015 before transferring to Clemson before the following season. After redshirting in 2016, Jackson played in a total of four games for the Tigers the next two seasons.

Obviously, Jackson never got the chance to take the field for the Sooners.
