Jackson worked with the first-team offense at times in Thursday's joint practices with Tennessee, the Minneapolis Star Tribune reports.
Jackson appears back to full speed after suffering a knee injury early in training camp. He's getting time with the first and second units with Jordan Addison sidelined with a concussion. Jackson has had an impressive camp and is making a strong case to win a final spot on the roster, but it's still more likely he ends up on the practice squad.
