Acker (groin) played a team-high 41 snaps at cornerback in the Chiefs' preseason opener against the 49ers.
Acker left practice with a groin injury back in June, but it appears as though he's back to full strength after putting together a solid outing to kick off the preseason. While Acker did take the most snaps, he'll likely still be fighting for a depth spot at cornerback for the rest of training camp.
