Alexander had one tackle and played on 50 of the defense's 69 snaps in Sunday's loss at Cincinnati.
He worked as the primary nickel and slot cornerback. Alexander gave up three receptions on four throws targeted at him for 32 yards, according to Pro Football Focus, which was better than most of his teammates in the secondary. He should have a steady role in the secondary in his return to the Vikings after one season with the Bengals.
