Rookie third-round draft pick Cameron Dantzler, who worked his way past first-rounder Jeff Gladney to win the nickel cornerback job for last week's Vikings season opener, has been listed as out with a rib injury for Sunday's game at Indianapolis.
Gladney, who played mostly special teams last week, is an option against the Colts.
"He's like all these young guys," coach Mike Zimmer said. "It's a continual work in progress. Working on techniques, working on alignments, working on different things. He's a great kid. Tough, competitive and I think he's going to be a really good player in due time.
