It appears Aidan Harrison’s time in Columbia has come to an end.

That’s due to the fact the redshirt freshman defensive back has just entered the NCAA transfer portal, according to Rivals Portal.

Harrison signed with Mizzou as a member of the 2019 recruiting cycle, the final full class of the Barry Odom era, as a three-star prospect from Michigan.

After appearing in nine games during his true freshman season, Harrison did not see the field for the Tigers in 2020.

Here is his bio listed on the Missouri team site:

2019 SEASON
Played in eight games during his true freshman season, seeing time primarily on special teams … Did not record any statistics, but the coaches are high on his athleticism and play-making ability as he should make an impact in the secondary throughout his career.
