All along, it looked like Austin was going to make the team as one of the Lions' backups on the interior of the offensive line. That didn't end up happening, though. After a somewhat inconsistent preseason, Austin was let go, indicating that he's not quite ready for a permanent backup role just yet. Chances are the Lions will try to put him back on their practice squad as they continue to develop him.
It seemed like Austin may have had a chance with Darren Keyton and Garrett Reynolds being released earlier, but the Lions have decided to go with one fewer offensive lineman on their roster.
